[Flang-RT] Support building no library (#187868)
Allow setting both FLANG_RT_ENABLE_SHARED and FLANG_RT_ENABLE_STATIC to
OFF at the same time.
This is extracted out of #171515 to make that PR a little smaller. By
itself it makes little sense since if not building either the `.a` or
the `.so`, you are not building anything. But with #171515, the module
files are still built, allowing building the modules files without the
library. This is mostly intended for GPGPU targets where building the
library is not always needed, but the module files are.

[mlir][linalg] Fix crash in greedy fusion when producer is fused into multiple consumers (#188561)
When the same producer is fused into multiple consumers in
fuseLinalgOpsGreedily, the second fusion can't find the original op in
the linalgOps vector (already replaced by the first fusion). llvm::find
returns end(), and writing to *end() caused an out-of-bounds stack write
that corrupted the adjacent OpBuilder's context pointer, leading to a
crash.
Fix by checking that find() returned a valid iterator before updating.
Fixes #122247

[MLIR] [Mem2Reg] Quick fix for dominance info invalidation (#188518)
We have identified a problem with DominanceInfo caching in Mem2Reg. It
appears to also be subject to incorrect cache hits when regions are
deleted, causing sporadic bugs that are difficult to test for.
This quick fix invalidates region that could be invalidated. This
attempts to not be too eager by only invalidating regions that are
exposed to a `finalizePromotion` call.
Ultimately it would be nice to have the ability to move the cached
information from one region to the next, but this is currently not
supported by DominanceInfo.
I was not able to produce a test for this as it is very sporadic. We
would need to be testing for a case where a region is re-allocated at
the same address as a previously erased region. If you know how to make
this sort of behavior consistent, I would be interested. Otherwise this
might require no testing.

Rclone v1.73 (using AWS SDK v2) signs the Accept-Encoding: identity
header as part of the SigV4 signature. Some reverse proxies modify that
header before it reaches the S3 gateway, so the server computes a
different signature and rejects the request. Setting
sign_accept_encoding = false excludes that header from the signature,
matching what the old rclone v1.67 did.

The update design says that "the system can be upgraded only to the next
train". This constraint turned out to be too strict.
Currently, the trains are as follows

[SampleFDO] Check pseudo probe descriptors for unused profile in stale profile matching (#179997)
If a function is fully optimized away in pre-link, it won't show up in
`SymbolMap` in post-link and the check of unused profile would treat it
as unused and allow it to be matched with unrelated functions. Extend
the check to cover such case in post link.
Also make `FuncToProfileNameMap` a MapVector so that we always get the
same iterator sequence out of it in `UpdateWithSalvagedProfiles`.
[HLSL][SPIRV] Add support for -g to generate NonSemantic Debug Info (#187051)
This adds two related changes to HLSL debug info support in the SPIR-V
backend. It's a first small step towards the plan I described in
https://discourse.llvm.org/t/hlsl-spirv-nsdi-debug-info-support-for-clang-dxc/90149.
## Tag HLSL shaders with `DW_LANG_HLSL` in the front-end
`GetSourceLanguage()` in `clang/lib/CodeGen/CGDebugInfo.cpp` checked
`LO.CPlusPlus` before `LO.HLSL`. Since HLSL is compiled as C++, the HLSL
check was never reached. Shaders compiled with `-g` were tagged with
`DW_LANG_C_plus_plus_14` instead of `DW_LANG_HLSL`. The NSDI pass
already had the correct mapping for `DW_LANG_HLSL` but it was never
triggered.
This fixes #136929 and #136995.
## Make `SPIRVEmitNonSemanticDI` activate automatically when `-g` is
used

[mlir][linalg] Improve inner tile size mismatch diagnostics in pack/unpack verifier (#188525)
Refactor the tile-size consistency check in
`commonVerifierPackAndUnPackOp` from a bulk `all_of` into an indexed
loop so that error messages include the offending dimension index and
the conflicting values, making failures easier to diagnose.
Before:
error: mismatch in inner tile sizes specified and shaped of tiled
dimension in the packed type
After (static/static mismatch):
error: mismatch in inner tile sizes specified and shaped of tiled
dimension in the packed type at index 1: got 8 \!= 4
After (dynamic tile, static packed dim):
error: mismatch in inner tile sizes specified at index 1: got static
shape 8 but dynamic tile size
