[GlobalISel] use constexpr LLT types when creating ISel data (#191574)
The GlobalISel uses a lookup table to map LLTs which is constructed
prior to initialization of extended LLT functionality, resulting in
ANY_SCALAR entries. During instruction selection, a hash-based
lookup is done on actual INTEGER/FLOAT LLTs. But hash values of
ANY_SCALAR do not match those of INTEGER/FLOAT, causing a failure.
Workaround is the use constexpr LLT, which encodes INTEGER/FLOAT LLT.

[flang] Fixed issues in nested LICM. (#192117)
First change is to check the hoisting safety for all nested
operations of the candidate. This prevents hoistings of
region operations as in the added test.
When hoisting operations from nested regions we have to
check every parent region for `canMoveOutOf`, otherwise,
illegal hoisting may happen. This second change is NFC,
because all operations that support `OperationMoveOpInterface`
currently also support `LoopLikeOpInterface` and their regions
are not considered for nested hoisting. Anyway, it is worth
fixing it.
[NFC][VPlan] Split `makeMemOpWideningDecisions` into subpasses
The idea is to have handling of strided memory operations (either from
https://github.com/llvm/llvm-project/pull/147297 or for VPlan-based
multiversioning for unit-strided accesses) done after some mandatory
processing has been performed (e.g., some types **must** be scalarized)
but before legacy CM's decision to widen (gather/scatter) or scalarize
has been committed.
And in longer term, we can uplift all other memory widening decision to
be done here directly at VPlan level. I expect this structure would also
be beneficial for that.
[clang] Fix assertion crash in CTAD for alias templates with non-dependent type (#191885)
When building deduction guides, clang assumes that the return type of
the deduction guide would always be a dependent type
(`TemplateSpecializationType`), but this is not true for invalid case,
where the alias RHS is a non-dependent class template specialization, it
is represented as a `RecordType` instead.
Fixes #190517.
[AArch64][clang][llvm] Add support for Armv9.7-A lookup table intrinsics
Add support for the following Armv9.7-A Lookup Table (lut)
instruction intrinsics:
SVE2.3
```c
// Variant is also available for: _u8 _mf8
svint8_t svluti6[_s8](svint8x2_t table, svuint8_t indices);
```
SVE2.3 and SME2.3
``` c
// Variants are also available for _u16_x2 and _f16_x2.
svint16_t svluti6_lane[_s16_x2](svint16x2_t table, svuint8_t indices, uint64_t imm_idx);
```
SME2.3
