Add standard Unicode case predicates isUpperCase and isLowerCase.
These predicates use the standard Unicode case properties and are more intuitive than isUpper and isLower.
Approved by CLC in https://github.com/haskell/core-libraries-committee/issues/90#issuecomment-1276649403.
Fixes #14589

rts: Use pthread_setname_np correctly on Darwin
As noted in #22206, pthread_setname_np on Darwin only supports
setting the name of the calling thread. Consequently we must introduce
a trampoline which first sets the thread name before entering the thread
entrypoint.

ncg/aarch64: Fix sub-word sign extension yet again
In adc7f108141a973b6dcb02a7836eed65d61230e8 we fixed a number of issues
to do with sign extension in the AArch64 NCG found by ghc/test-primops>.
However, this patch made a critical error, assuming that getSomeReg
would allocate a fresh register for the result of its evaluation.
However, this is not the case as `getSomeReg (CmmReg r) == r`.
Consequently, any mutation of the register returned by `getSomeReg` may
have unwanted side-effects on other expressions also mentioning `r`. In
the fix listed above, this manifested as the registers containing the
operands of binary arithmetic operations being incorrectly
sign-extended. This resulted in #22282.
Sadly, the rather simple structure of the tests generated
by `test-primops` meant that this particular case was not exercised.
Even more surprisingly, none of our testsuite caught this case.
Here we fix this by ensuring that intermediate sign extension is
performed in a fresh register.
Fixes #22282.

rts: ensure we are below maxHeapSize after returning megablocks
When the heap is heavily block fragmented the live byte size might be
low while the memory usage is high. We want to ensure that heap overflow
triggers in these cases.
We do so by checking that we can return enough megablocks to
under maxHeapSize at the end of GC.

rts: trigger a major collection if megablock usage exceeds maxHeapSize
When the heap is suffering from block fragmentation, live bytes might be
low while megablock usage is high.
If megablock usage exceeds maxHeapSize, we want to trigger a major GC to
try to recover some memory otherwise we will die from a heapOverflow at
the end of the GC.

DmdAnal: Look through unfoldings of DataCon wrappers (#22241)
Previously, the demand signature we computed upfront for a DataCon wrapper
lacked boxity information and was much less precise than the demand transformer
for the DataCon worker.
In this patch we adopt the solution to look through unfoldings of DataCon
wrappers during Demand Analysis, but still attach a demand signature for other
passes such as the Simplifier.
See `Note [DmdAnal for DataCon wrappers]` for more details.
Fixes #22241.

Add `Enum (Down a)` instance that swaps `succ` and `pred`
See https://github.com/haskell/core-libraries-committee/issues/51 for
discussion. The key points driving the implementation are the following
two ideas:
* For the `Int` type, `comparing (complement @Int)` behaves exactly as
an order-swapping `compare @Int`.
* `enumFrom @(Down a)` can be implemented in terms of `enumFromThen @a`,
if only the corner case of starting at the very end is handled specially

Update the check-exact infrastructure to match ghc-exactprint
GHC tests the exact print annotations using the contents of
utils/check-exact.
The same functionality is provided via
https://github.com/alanz/ghc-exactprint
The latter was updated to ensure it works with all of the files on
hackage when 9.2 was released, as well as updated to ensure users of
the library could work properly (apply-refact, retrie, etc).
This commit brings the changes from ghc-exactprint into
GHC/utils/check-exact, adapting for the changes to master.
Once it lands, it will form the basis for the 9.4 version of
ghc-exactprint.

Fix GHCis interaction with tag inference.
I had assumed that wrappers were not inlined in interactive mode.
Meaning we would always execute the compiled wrapper which properly
takes care of upholding the strict field invariant.
This turned out to be wrong. So instead we now run tag inference even
when we generate bytecode. In that case only for correctness not
performance reasons although it will be still beneficial for runtime
in some cases.
I further fixed a bug where GHCi didn't tag nullary constructors
properly when used as arguments. Which caused segfaults when calling
into compiled functions which expect the strict field invariant to
be upheld.

Allow configuration of error message printing
This MR implements the idea of #21731 that the printing of a diagnostic
method should be configurable at the printing time.
The interface of the `Diagnostic` class is modified from:
```
class Diagnostic a where
diagnosticMessage :: a -> DecoratedSDoc
diagnosticReason :: a -> DiagnosticReason
diagnosticHints :: a -> [GhcHint]
```
to
```
class Diagnostic a where
type DiagnosticOpts a
defaultDiagnosticOpts :: DiagnosticOpts a
diagnosticMessage :: DiagnosticOpts a -> a -> DecoratedSDoc
diagnosticReason :: a -> DiagnosticReason
diagnosticHints :: a -> [GhcHint]
```
and so each `Diagnostic` can implement their own configuration record
which can then be supplied by a client in order to dictate how to print
out the error message.
At the moment this only allows us to implement #21722 nicely but in
future it is more natural to separate the configuration of how much
information we put into an error message and how much we decide to print
out of it.

Add -fsuppress-error-contexts to disable printing error contexts in errors
In many development environments, the source span is the primary means
of seeing what an error message relates to, and the In the expression:
and In an equation for: clauses are not particularly relevant. However,
they can grow to be quite long, which can make the message itself both
feel overwhelming and interact badly with limited-space areas.
It's simple to implement this flag so we might as well do it and give
the user control about how they see their messages.

Add VecSlot for unboxed sums of SIMD vectors
This patch adds the missing `VecRep` case to `primRepSlot` function and

to be written and compiled.

Remove SIMD conversions
This patch makes it so that packing/unpacking SIMD
vectors always uses the right sized types, e.g.
unpacking a Word16X4# will give a tuple of Word16#s.
As a result, we can get rid of the conversion instructions
that were previously required.

Cmm Lint: relax SIMD register assignment check
As noted in #22297, SIMD vector registers can be used
to store different kinds of values, e.g. xmm1 can be used
both to store integer and floating point values.
The Cmm type system doesn't properly account for this, so
we weaken the Cmm register assignment lint check to only
compare widths when comparing a vector type with its
allocated vector register.

More precise types for fields of OverlappingInstances and UnsafeOverlap in TcSolverReportMsg
It's clear from asserts in `GHC.Tc.Errors` that `overlappingInstances_matches`
and `unsafeOverlapped` are supposed to be non-empty, and `unsafeOverlap_matches`
contains a single instance, but these invariants are immediately lost afterwards
and not encoded in types. This patch enforces the invariants by pattern matching
and makes types more precise, avoiding asserts and partial functions such as `head`.

TyCon.

remove a no-warn directive from GHC.Cmm.ContFlowOpt
This patch is motivated by the desire to remove the {-# OPTIONS_GHC
-fno-warn-incomplete-patterns #-} directive at the top of
GHC.Cmm.ContFlowOpt. (Based on the text in this coding standards doc, I
understand it's a goal of the project to remove such directives.) I
chose this task because I'm a new contributor to GHC, and it seemed like
a good way to get acquainted with the patching process.
In order to address the warning that arose when I removed the no-warn
directive, I added a case to removeUnreachableBlocksProc to handle the
CmmData constructor. Clearly, since this partial function has not been
erroring out in the wild, its inputs are always in practice wrapped by
the CmmProc constructor. Therefore the CmmData case is handled by a
precise panic (which is an improvement over the partial pattern match
from before).

build: get rid of `HAVE_TIME_H`
As advertized by `autoreconf`:
> All current systems provide time.h; it need not be checked for.
Hence, remove the check for it in `configure.ac` and remove conditional
inclusion of the header in `HAVE_TIME_H` blocks where applicable.
The `time.h` header was being included in various source files without a
`HAVE_TIME_H` guard already anyway.

rts: remove use of `TIME_WITH_SYS_TIME`
`autoreconf` will insert an `m4_warning` when the obsolescent
`AC_HEADER_TIME` macro is used:
> Update your code to rely only on HAVE_SYS_TIME_H,
> then remove this warning and the obsolete code below it.
> All current systems provide time.h; it need not be checked for.
> Not all systems provide sys/time.h, but those that do, all allow
> you to include it and time.h simultaneously.
Presence of `sys/time.h` was already checked in an earlier
`AC_CHECK_HEADERS` invocation, so `AC_HEADER_TIME` can be dropped and
guards relying on `TIME_WITH_SYS_TIME` can be reworked to
(unconditionally) include `time.h` and include `sys/time.h` based on
`HAVE_SYS_TIME_H`.
Note the documentation of `AC_HEADER_TIME` in (at least) Autoconf 2.67
says
> This macro is obsolescent, as current systems can include both files
> when they exist. New programs need not use this macro.
