EPA: Replace Anchor with EpaLocation
An Anchor has a location and an operation, which is either that it is
unchanged or that it has moved with a DeltaPos
data Anchor = Anchor { anchor :: RealSrcSpan
, anchor_op :: AnchorOperation }
An EpaLocation also has either a location or a DeltaPos
data EpaLocation = EpaSpan !RealSrcSpan !(Strict.Maybe BufSpan)
| EpaDelta !DeltaPos ![LEpaComment]
Now that we do not care about always having a location in the anchor,
we remove Anchor and replace it with EpaLocation
We do this with a type alias initially, to ease the transition.
The alias will be removed in time.
We also have helpers to reconstruct the AnchorOperation from an
EpaLocation. This is also temporary.
Updates Haddock submodule

Suppress duplicate librares linker warning of new macOS linker
Fixes #24167
XCode 15 introduced a new linker which warns on duplicate libraries being
linked. To disable this warning, we pass -Wl,-no_warn_duplicate_libraries as
suggested by Brad King in CMake issue #25297.
This flag isn't necessarily available to other linkers on darwin, so we must
only configure it into the CC linker arguments if valid.

testsuite: Encoding test witnesses recent iconv bug is fragile
A regression in the new iconv() distributed with XCode 15 and MacOS
Sonoma causes the test 'encoding004' to fail in the CP936 roundrip.
We mark this test as fragile until this is fixed upstream (rather than
broken, since previous versions of iconv pass the test)
See #24161

testsuite: Update to LC_ALL=C no longer being ignored in darwin
MacOS seems to have fixed an issue where it used to ignore the variable
`LC_ALL` in program invocations and default to using Unicode.
Since the behaviour seems to be fixed to account for the locale
variable, we mark tests that were previously broken in spite of it as
fragile (since they now pass in recent macOS distributions)
See #24161

darwin: Fix single_module is obsolete warning
In XCode 15's linker, -single_module is the default and otherwise
passing it as a flag results in a warning being raised:
ld: warning: -single_module is obsolete
This patch fixes this warning by, at configure time, determining whether
the linker supports -single_module (which is likely false for all
non-darwin linkers, and true for darwin linkers in previous versions of
macOS), and using that information at runtime to decide to pass or not
the flag in the invocation.
Fixes #24168

testsuite: Skip MultiLayerModulesTH_Make on darwin
The recent toolchain upgrade on darwin machines resulted in the
MultiLayerModulesTH_Make test metrics varying too much from the
baseline, ultimately blocking the CI pipelines.
This commit skips the test on darwin to temporarily avoid failures due
to the environment change in the runners. However, the metrics
divergence is being investigated still (tracked in #24177)

configure: check target (not build) understands -no_compact_unwind
Previously, we were branching on whether the build system was darwin to
shortcut this check, but we really want to branch on whether the target
system (which is what we are configuring ld_prog for) is darwin.

JS: Fix missing variable declarations
The JStg IR update was missing some local variable declarations
that were present earlier, causing global variables to be used
implicitly (or an error in JavaScript strict mode).
This adds the local variable declarations again.

users-guide: Fix links to libraries from the users-guide.
The unit-ids generated in c1a3ecde720b3bddc2c8616daaa06ee324e602ab include the
package name, so we don't need to explicitly add it to the links.

Fix unusable units and module reexport interaction (#21097)
This commit fixes an issue with ModUnusable introduced in df0f148feae.
In mkUnusableModuleNameProvidersMap we traverse the list of unusable
units and generate ModUnusable origin for all the modules they contain:
exposed modules, hidden modules, and also re-exported modules. To do
this we have a two-level map:
ModuleName -> Unit:ModuleName (aka Module) -> ModuleOrigin
So for each module name "M" in broken unit "u" we have:
"M" -> u:M -> ModUnusable reason
However in the case of module reexports we were using the *target*
module as a key. E.g. if "u:M" is a reexport for "X" from unit "o":
"M" -> o:X -> ModUnusable reason
Case 1: suppose a reexport without module renaming (u:M -> o:M) from
unusable unit u:
"M" -> o:M -> ModUnusable reason
Here it's claiming that the import of M is unusable because a reexport
from u is unusable. But if unit o isn't unusable we could also have in
the map:
"M" -> o:M -> ModOrigin ...
Issue: the Semigroup instance of ModuleOrigin doesn't handle the case
(ModUnusable <> ModOrigin)
Case 2: similarly we could have 2 unusable units reexporting the same module
without renaming, say (u:M -> o:M) and (v:M -> o:M) with u and v
unusable. It gives:
"M" -> o:M -> ModUnusable ... (for u)
"M" -> o:M -> ModUnusable ... (for v)
Issue: the Semigroup instance of ModuleOrigin doesn't handle the case
(ModUnusable <> ModUnusable).
This led to #21097, #16996, #11050.
To fix this, in this commit we make ModUnusable track whether the module
used as key is a reexport or not (for better error messages) and we use
the re-export module as key. E.g. if "u:M" is a reexport for "o:X" and u
is unusable, we now record:
"M" -> u:M -> ModUnusable reason reexported=True
So now, we have two cases for a reexport u:M -> o:X:
- u unusable: "M" -> u:M -> ModUnusable ... reexported=True
- u usable: "M" -> o:X -> ModOrigin ... reexportedFrom=u:M
The second case is indexed with o:X because in this case the Semigroup
instance of ModOrigin is used to combine valid expositions of a module
(directly or via reexports).
Note that module lookup functions select usable modules first (those who
have a ModOrigin value), so it doesn't matter if we add new ModUnusable
entries in the map like this:
"M" -> {
u:M -> ModUnusable ... reexported=True
o:M -> ModOrigin ...
}
The ModOrigin one will be used. Only if there is no ModOrigin or
ModHidden entry will the ModUnusable error be printed. See T21097 for an
example printing several reasons why an import is unusable.

AArch64: Remove unused instructions
As these aren't ever emitted, we don't even know if they work or will
ever be used. If one of them is needed in future, we may easily re-add
it.
Deleted instructions are:
- CMN
- ANDS
- BIC
- BICS
- EON
- ORN
- ROR
- TST
- STP
- LDP
- DMBSY
