[Support] [BLAKE3] Fix compilation with CMAKE_OSX_ARCHITECTURES
With CMake, one can build for multiple macOS architectures
at the same time by setting CMAKE_OSX_ARCHITECTURES to multiple
architectures (avoiding needing to do two separate builds and
gluing the binaries together after the build).
In this case, while targeting x86_64 and arm64, neither IS_X64
nor IS_ARM64 is set, while compilation of the individual source
files will hit those cases (in either architecture mode).
Therefore, if we on the CMake level decide not to include the
architecture specific SIMD implementation files, also tell the
source this explicitly by passing the defines indicating that we
don't expect to use them.
Such a build clearly is less ideal than explicitly targeting one
architecture at a time if it won't include all the SIMD optimizations,
but that's a tradeoff that is up to the one deciding to do such an
universal build.
This also fixes builds for i386. The blake3 source code automatically
enables the SIMD implementations when building for i386, but we don't
provide the sources for that build configuration.

[lld][COFF] Fix TypeServerSource lookup on GUID collisions
Microsoft shipped a bunch of PDB files with broken/invalid GUIDs
which lead lld to use 0xFF as the key for these files in an internal
cache. When multiple files have this key it will lead to collisions
and confused symbol lookup.
Several approaches to fix this was considered. Including making the key
the path to the PDB file, but this requires some filesystem operations
in order to normalize the file path.
Since this only happens with malformatted PDB files and we haven't
seen this before they malformatted files where shipped with visual
studio we probably shouldn't optimize for this use-case.
Instead we now just don't insert files with Guid == 0xFF into the
cache map and warn if we get collisions so similar problems can be
found in the future instead of being silent.

and removes the explicit flag set for all of the current list options.
The new parsing for comma separation of ListOption also adds in support
for skipping over delimited sub-ranges (i.e. {}, [], (), "", ''). This
more easily supports nested options that use those as part of the
format, and this constraint (balanced delimiters) is already codified
in the syntax of pass pipelines.

EmitFuncArgumentDbgValue relied on a boolean flag IsDbgDeclare both to signal
that a DBG_VALUE should be made to be indirect /and/ that the original intrinsic
was a dbg.declare. This is no longer always true if we add support for handling
dbg.addr since we will have an indirect DBG_VALUE that is a different intrinsic
from dbg.declare.
With that in mind, in this NFC patch, we prepare for future fixes by introducing
a 3 case-enum argument to EmitFuncArgumentDbgValue that allows the caller to
explicitly specify how the argument's DBG_VALUE should be emitted. This then
allows us to turn the indirect checks into a != FuncArgumentDbgValueKind::Value
and prepare us for a future where we add support here for llvm.dbg.addr
directly.

- Macros must not be defined adjacent to other preprocessor directives.
- Macros must not be used in preprocessor conditions
Each cluster of macros meeting the above constraints is presumed to
be a set of values suitable for replacement by an anonymous enum.
From there, a developer can give the anonymous enum a name and
continue refactoring to a scoped enum if desired. Comments on the

are preserved in the output. No formatting is assumed in the provided

The check cppcoreguidelines-macro-to-enum is an alias for this check.

[flang] add evaluate::IsAllocatableDesignator helper
Previously, some semantic checks that are checking if an entity is an
allocatable were relying on the expression being a designator whose
last symbol has the allocatable attribute.
This is wrong since this was considering substrings and array sections of
allocatables as being allocatable. This is wrong (see NOTE 2 in
Fortran 2018 section 9.5.3.1).
Add evaluate::IsAllocatableDesignator to correctly test this.
Also add some semantic tests for ALLOCATED to test the newly added helper.
Note that ifort and nag are rejecting coindexed-named-object in
ALLOCATED (`allocated(coarray_scalar_alloc[2])`).
I think it is wrong given allocated argument is intent(in) as per
16.2.1 point 3.
So 15.5.2.6 point 4 regarding allocatable dummy is not violated (If the actual
argument is a coindexed object, the dummy argument shall have the INTENT (IN)
attribute.) and I think this is valid. gfortran accepts it.
The need for this helper was exposed in https://reviews.llvm.org/D122779.

[RISCV][AMDGPU][TargetLowering] Special case overflow expansion for (uaddo X, 1).
If we expand (uaddo X, 1) we previously expanded the overflow calculation
as (X + 1) <u X. This potentially increases the live range of X and
can prevent X+1 from reusing the register that previously held X.
Since we're adding 1, overflow only occurs if X was UINT_MAX in which
case (X+1) would be 0. So this patch adds a special case to expand
the overflow calculation to (X+1) == 0.
This seems to help with uaddo intrinsics that get introduced by
CodeGenPrepare after LSR. Alternatively, we could block the uaddo
transform in CodeGenPrepare for this case.

Fix behavior of ifuncs with 'used' extern "C" static functions
We expect that `extern "C"` static functions to be usable in things like
inline assembly, as well as ifuncs:
See the bug report here: https://github.com/llvm/llvm-project/issues/54549
However, we were diagnosing this as 'not defined', because the
ifunc's attempt to look up its resolver would generate a declared IR
function.
Additionally, as background, the way we allow these static extern "C"
functions to work in inline assembly is by making an alias with the C
mangling in MOST situations to the version we emit with
internal-linkage/mangling.
The problem here was multi-fold: First- We generated the alias after the
ifunc was checked, so the function by that name didn't exist yet.
Second, the ifunc's generation caused a symbol to exist under the name
of the alias already (the declared function above), which suppressed the
alias generation.
This patch fixes all of this by moving the checking of ifuncs/CFE aliases
until AFTER we have generated the extern-C alias. Then, it does a
'fixup' around the GlobalIFunc to make sure we correct the reference.

[mlir][sparse] Moving `delete coo` into codegen instead of runtime library
Prior to this change there were a number of places where the allocation and deallocation of SparseTensorCOO objects were not cleanly paired, leading to inconsistencies regarding whether each function released its tensor/coo arguments or not, as well as making it easy to run afoul of memory leaks, use-after-free, or double-free errors. This change cleans up the codegen vs runtime boundary to resolve those issues. Now, the only time the runtime library frees an object is either (a) because it's a function explicitly designed to do so, or (b) because the allocated object is entirely local to the function and would be a memory leak if not released. Thus, now the codegen takes complete responsibility for releasing any objects it caused to be allocated.
