[MemCpyOpt] Work around PR54682
As discussed on https://github.com/llvm/llvm-project/issues/54682,
MemorySSA currently has a bug when computing the clobber of calls
that access loop-varying locations. I think a "proper" fix for this
on the MemorySSA side might be non-trivial, but we can easily work
around this in MemCpyOpt:
Currently, MemCpyOpt uses a location-less getClobberingMemoryAccess()
call to find a clobber on either the src or dest location, and then
refines it for the src and dest clobber. This was intended as an
optimization, as the location-less API is cached, while the
location-affected APIs are not.
However, I don't think this really makes a difference in practice,
because I don't think anything will use the cached clobbers on
those calls later anyway. On CTMark, this patch seems to be very
mildly positive actually.
So I think this is a reasonable way to avoid the problem for now,
though MemorySSA should also get a fix.

[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.

[trace][intel pt] Handle better tsc in the decoder
A problem that I introduced in the decoder is that I was considering TSC decoding
errors as actual instruction errors, which mean that the trace has a gap. This is
wrong because a TSC decoding error doesn't mean that there's a gap in the trace.
Instead, now I'm just counting how many of these errors happened and I'm using
the `dump info` command to check for this number.
Besides that, I refactored the decoder a little bit to make it simpler, more
readable, and to handle TSCs in a cleaner way.

prevents bugs like:
```
void fun(IntegerRelation a, IntegerRelation b) {
IntegerPolyhedron c = a.intersect(b);

```
Here, `a.intersect(b)` will return `IntegerRelation`, which will be implicitly
converted to `PresburgerSpace` and will use the `PresburgerSpace` constructor
for IntegerPolyhedron. Leading to loss of any constraints in the intersection
of `a` and `b`. After this patch, this will give a compile error.

[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.
Discussion about the root issue and the approach to this fix can be found on Github: https://github.com/llvm/llvm-project/issues/54487

[mlir:PassOption] Rework ListOption parsing and add support for std::vector/SmallVector options
ListOption currently uses llvm::cl::list under the hood, but the usages
of ListOption are generally a tad different from llvm::cl::list. This
commit codifies this by making ListOption implicitly comma separated,
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.

[debug-info] As an NFC commit, refactor EmitFuncArgumentDbgValue so that it can be extended to support llvm.dbg.addr.
The reason why I am making this change is that before this commit,
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.
