[InstCombine] Add tests for inbounds handling in loop invariant GEP fold (NFC)

[InstCombine] Always create new GEPs when swapping GEPs

As the long explanatory comment attests, performing the modification
in place is pretty tricky. Drop this unnecessary complexity and
always create new instructions.

This should be NFC-ish, but can probably cause difference due to
worklist order.

[flang][OpenMP] Check for occurrence of multiple list items in nontemporal clause for simd directive

This patch implements the following semantic check:

A list-item cannot appear in more than one nontemporal clause.

[InstCombine] When swapping GEPs, only keep inbounds if both are

If only one of the GEPs is inbounds, then after swapping, there is
no guarantee that one of them will be inbounds as well
(see e.g. https://alive2.llvm.org/ce/z/agaCnp).

This is only a partial fix, because even if both are inbounds, the
result is not necessarily inbounds (if the offsets have different
signs).

Change build_llvm_package.bat to build_llvm_release.bat

We don't build snapshot packages anymore, so repurpose this
for doing release builds instead.

[mlir] add VectorizeOp to structured transform ops

Vectorization is a key transformation to achieve high performance on most
architectures. In the transform dialect, vectorization is implemented as a
parameterizable transform op. It currently applies to a scope of payload IR
delimited by some isolated-from-above op, mainly because several enabling
transformations (such as affine simplification) are needed to perform
vectorization and these transformation would apply to ops other than the "main"
computational payload op. A separate "navigation" transform op that obtains the
isolated-from-above ancestor of an op is introduced in the core transform
dialect. Even though it is currently only useful for vectorization,
isolated-from-above ops are a common anchor for transformations (usually
implemented as passes) that is likely to be reused in the future.

[mlir] provide Python bindings for the Transform dialect

Python bindings for extensions of the Transform dialect are defined in separate
Python source files that can be imported on-demand, i.e., that are not imported
with the "main" transform dialect. This requires a minor addition to the
ODS-based bindings generator. This approach is consistent with the current
model for downstream projects that are expected to bundle MLIR Python bindings:
such projects can include their custom extensions into the bundle similarly to
how they include their dialects.

[HLSL] Enable vector types for hlsl.

[TwoAddressInstructionPass] Special processing of STATEPOINT instruction.

STATEPOINT is a special pseudo instruction which represent Moving GC semantic to LLVM.
Every tied def/use VReg pair in STATEPOINT represent same physical register which can
'magically' change during call wrapped by statepoint.
(By construction, tied use operand  is not live across  STATEPOINT).

This means that when converting into two-address form, there is not need to insert COPY
instruction before stateppoint, what TwoAddressInstruction pass does for 'regular'
instructions.

[gn build] Port e576280380d3

Fix warning for unused variable in the non-assert build (NFC)

[ODRHash][NFC] Add missing 'select' case for `ODRMismatchDecl`.

No test changes because `err_module_odr_violation_mismatch_decl_unknown`
is a catch-all when custom diagnostic is missing. And missing custom
diagnostic we should fix by implementing it, not by improving the
general case. But if we pass enum value not covered by 'select', clang
can crash, so protect against that.

[Support] Make report_fatal_error respect its GenCrashDiag argument so it doesn't generate a backtrace

There are a few places where we use report_fatal_error when the input is broken.
Currently, this function always crashes LLVM with an abort signal, which
then triggers the backtrace printing code.
I think this is excessive, as wrong input shouldn't give a link to
LLVM's github issue URL and tell users to file a bug report.
We shouldn't print a stack trace either.

This patch changes report_fatal_error so it uses exit() rather than
abort() when its argument GenCrashDiag=false.
