This patch improves the compile_flags.txt config used to power clangd
for the rts C codebase. The flags in the file are sampled & deduped
from a real stage1 build with clang-19 and vastly improves the IDE
accuracy when hacking the rts.
For maximum code coverage under the default settings,
compile_flags.txt defaults to threaded+profiled+dynamic+debug way.
This does not mean profdyn needs to be actually built in _build/stage1
for IDE to work. To activate IDE for other RTS ways, simply remove one
of the -D flags at the end of compile_flags.txt and restart clangd.

Considering trees containing untracked files as dirty is a bridge too
far. The chance of an untracked file significantly affecting measured
performanced metrics is quite small whereas not collecting measurements
is quite inconvenient for some workflows. We now ignore untracked files
in the dirtiness check.

Previously we had unnecessary (and incorrect) platform-dependent casts
to turn `OSThreadIds`s into a integer. We now just uniformly cast first
to a `uintptr_t` (which is always safe, regardless of whether
`OSThreadId` is a pointer), and then cast to the desired integral type.
This fixes a warning on musl platforms.

Basic changes:
* Change `catch` function to propagate exceptions using the
WhileHandling mechanism.
* Introduce `catchNoPropagate`, which does the same as before, but
passes an exception which can be rethrown.
* Introduce `rethrowIO` combinator, which rethrows an exception with a
context and doesn't add a new backtrace.
* Introduce `tryWithContext` for a variant of `try` which can rethrow
the exception with it's original context.
* onException is modified to rethrow the original error rather than
creating a new callstack.
* Functions which rethrow in GHC.Internal.IO.Handle.FD,
GHC.Internal.IO.Handle.Internals, GHC.Internal.IO.Handle.Text, and
GHC.Internal.System.IO.Error are modified to not add a new callstack.

This commit changes the Exception instance of SomeException to *simply*
display the underlying exception in `displayException`. The augmented
exception message that included the type and backtrace of the exception
are now only printed on a call to `displayExceptionWithInfo`.
At a surface level, existing programs should behave the same since the
`uncaughtExceptionHandler`, which is responsible for printing out uncaught
exceptions to the user, will use `displayExceptionWithInfo` by default.
However, unlike the instance's `displayException` method, the
`uncaughtExceptionHandler` can be overriden with
`setUncaughtExceptionHandler`. This makes the extra information opt-in
without fixing it the instance, which can be valuable if your program
wants to display uncaught exceptions to users in a user-facing way
(ie without backtraces).
This is what was originally agreed for CLC#231 or CLC#261 with regard to
the type of the exception information.
The call stack also becoming part of the default handler rather than the
Exception instance is an ammendment to CLC#164.
Discussion of the ammendment is part of CLC#285.

When running the program with `runhaskell`/`runghc` the backtrace should
match the backtrace one would get by compiling and running the program.
But currently, an exception thrown in a program interpreted with
`runhaskell` will:
* Not include the original exception backtrace at all
* Include the backtrace from the internal GHCi/ghc rethrowing of the
original exception
This commit fixes this divergence by not annotating the ghc(i) backtrace
(with NoBacktrace) and making sure that the backtrace of the original
exception is serialized across the boundary and rethrown with the
appropriate context.

MultiLayerModules. Unfortunately, T3294 regresses on aarch64-linux-deb12
by 1% allocations. Since this patch must be merged for 9.12 ASAP, we
will not be able to investigate the slight regression on this platform
in time.

We were reserving the wrong kind of adjustor context (the generic
`AdjustorContext` used by other adjustor implementations, rather than
the i386-specific `CCallContext`) to return the adjustor context while
freeing, resulting in #25485.
Fixes #25485.

This commit fixes the implementation of 'regUsageOfInstr' for vector
operations that take an 'Operand' as the destination, by ensuring that
when the destination is an address then the address should be *READ*,
and not *WRITTEN*.
Getting this wrong is a disaster, as it means the register allocator
has incorrect information, which can lead to it discard stores to
registers, segfaults ensuing.

Introduces `ReachabilityIndex`, an index constructed from a
`GHC.Data.Graph.Directed` `Graph` that supports fast reachability
queries (in $O(1)$). This abstract data structure is exposed from
`GHC.Data.Graph.Directed.Reachability`.
This index is constructed from the module graph nodes and cached in
`ModuleGraph`, enabling efficient reachability queries on the module
graph. Previously, we'd construct a Map of Set of ModuleGraph nodes
which used a lot of memory (`O(n^2)` in the number of nodes) and cache
that in the `ModuleGraph`. By using the reachability index we get rid of
this space leak in the module graph -- even though the index is still
quadratic in the number of modules, it is much, much more space
efficient due to its representation using an IntMap of IntSet as opposed
to the transitive closure we previously cached.
In a memory profile of MultiLayerModules with 100x100 modules, memory
usage improved from 6GB residency to 2.8GB, out of which roughly 1.8GB
are caused by a second space leak related to ModuleGraph. On the same
program, it brings compile time from 7.5s to 5.5s.
Note how we simplify `checkHomeUnitsClosed` in terms of
`isReachableMany` and by avoiding constructing a second graph with the
full transitive closure -- it suffices to answer the reachability query
on the full graph without collapsing the transitive closure completely
into nodes.
Unfortunately, solving this leak means we have to do a little bit more
work since we can no longer cache the result of turning vertex indices
into nodes. This results in a slight regression in MultiLayerModulesTH_Make,
but results in large performance and memory wins when compiling large
amounts of modules.

This patch removes the unused `GHC.Linker.Loader.loadExpr` function.
It was moved from `GHC.Runtime.Linker.linkExpr` in `ghc-9.0` to
`GHC.Linker.Loader.loadExpr` in `ghc-9.2`, and remain completely
unused and untested ever since. There's also no third party user of
this function to my best knowledge, so let's remove this. Anyone who
wants to write their own GHC API function to load bytecode can consult
the source code in older release branches.

temporary fix of the problem descriped in https://gitlab.haskell
.org/ghc/ghc/-/issues/25495. This commit requires that the LLVM
used contains the code of commit 9dd1d451d9719aa91b3bdd59c0c6679
83e1baf05, i.e., version 8.0 and later. Actually we should not
rely on LLVM, so the only way to solve this problem is to implement
the LoongArch backend.

Currently the ExecPage facility has two users:
* GHCi, for constructing info tables, and
* the adjustor allocation path
Despite neither of these have any spatial locality constraints ExecPage
was using the linker's `mmapAnonForLinker`, which tries hard to ensure
that mappings end up nearby the executable image. This makes adjustor
allocation needlessly subject to fragmentation concerns.
We now instead return less constrained mappings, improving the
robustness of the mechanism.

The combination of ScopedTypeVariables + TypeApplications now no longer

In Hadrian, we are careful to use -/- rather than </>, in order to use
/ instead of \ in filepaths. However, this gets ruined by the use of
makeAbsolute from System.Directory, which, on Windows, changes back
forward slashes to backslashes.

Previously the structure of `mmapInRegion` concealed a subtle bug
concerning handling of `mmap` returning mappings below the beginning of
the desired region. Specifically, we would reset `p = result + bytes`
and then again reset `p = region->start` before looping around for
another iteration. This resulted in an infinite loop on FreeBSD.
Fixes #25492.

The 'ModuleGraph' abstraction represents the relationship and strucutre
of the modules being compiled. This structure is meant to be constructed
once at the start of compilation, and never changed again.
However, it's exposed interface was confusing and exposed too many
footguns which led to inneficient usages of the ModuleGraph. This commit
improves significantly the exported interface of ModuleGraph, taking
into consideration the recent improvements around reachability queries.
Since the ModuleGraph graphs and related structures (HPT, EPS) are
performance critical in the sense that somewhat simple mistakes can
cause bad leaks and non-linear memory usage, we want to have proper APIs
that guide efficient usage. This is a good step in that direction.
