[mlir][SPIR-V] Support bitwise and/or/xor in gpu reduction lowering (#202351)

[RISCV] Don't move memory instructions across calls in isSafeToMove (#212236)

RISCVInstrInfo::isSafeToMove scans the instructions between From and To
to decide whether a memory instruction can be moved, but it only treated
mayStore() instructions as barriers. Calls on RISC-V are modeled with
isCall() and a register mask rather than mayStore(), so a load could be
moved across a call even though the callee may clobber the loaded
memory.

RISCVVectorPeephole::foldVMergeToMask uses this helper via ensureDominates()
to sink a load into a masked load when folding it into a vmerge, which
produced wrong code when the load was sunk past a call.

Instead of hand-rolling the barrier check, call MachineInstr::isSafeToMove
on each intervening instruction to populate SawStore. That is the same
helper used on From below, and it already treats calls (as well as PHIs
and ordered memory references) as stores.

This fixes #212226.

[clang][NFC] fold ExpressionTraits and TypeTraits helpers into BuiltinTraits (#210838)

ExpressionTraits.h defines utilities such as `getTraitName`,
`getTraitSpelling` and an enumeration for expression traits. All other
overloads of these utilities can be found in TypeTraits.h - this patch
combines them to BuiltinTraits.h/cpp.

This is a followup patch for

[llvm][release] Build openmp as runtime in test-release.sh (#212111)

`test_release.sh` tries to build `openmp` as a project, which breaks the
build:

```
CMake Error at CMakeLists.txt:155 (message):

  Support for the LLVM_ENABLE_PROJECTS=openmp build mode has been removed.
  Please switch to the bootstrapping build

      cmake -S <llvm-project>/llvm -B build -DLLVM_ENABLE_PROJECTS=clang -DLLVM_ENABLE_RUNTIMES=openmp

  or to the runtimes default build

      cmake -S <llvm-project>/runtimes -B build -DLLVM_ENABLE_RUNTIMES=openmp
```

This patch switches it to a runtime to match.

[sanitizer_common][tests] Skip MemoryMapping::ParseUnixMemoryProfile … (#212114)

…etc. on NetBSD

The `Sanitizer-x86_64-Test` test doesn't link on NetBSD/amd64 10.1:

```
/usr/bin/ld: /usr/bin/ld: DWARF error: invalid or unhandled FORM value: 0x25
SANITIZER_TEST_OBJECTS.sanitizer_procmaps_test.cpp.x86_64.o: in function `__sanitizer::MemoryMapping_ParseUnixMemoryProfile_Test::TestBody()':

[PAC][clang][test] Fix incorrect usage of `-NOT` suffix for FileCheck

Previously, `-NOT` checks were not doing what was intended: checking
that given strings are not present within the same line where other
patterns are confirmed present by other checks. `-NOT` semantics is
checking pattern absense in between other checks, not total absense.

This patch makes use of `--implicit-check-not` instead for this purpose.

[LoopUnroll] Allow vector types for minmax reductions (#207630)

Our downstream patched RecurrenceDescriptor in IVDescriptors.cpp to
recognize min/max reductions on vector-typed phis. After ffa02793,
vector min/max intrinsic reductions now flow into getReductionIdentity()
with vector type and then runtime-unroll-reductions-min-max.ll test
crashed.
This PR upstreams our RecurrenceDescriptor change to avoid further
downstream change to LoopUtils.cpp (in this PR) that fixes the crash.

LIT change in runtime-unroll-reductions-min-max.ll shows a long serial
reduction chain now breaks into two independent ones, which is the
purpose of unroll-add-parallel-reductions.

[Hexagon] Fix missing requires assert for swp-epilog-phi12.mir (#212062)

[SPIR-V] Fix hex float exponent for f64 Inf/NaN literals (#212295)

The asm printer hardcoded the f32 exponent (+128) when printing Inf/NaN
as hex floats, so f64 Inf/NaN literals were misencoded and silently
reassembled as finite values by consumers

Derive the exponent from the operand actual semantic instead

[lldb][AArch64][Linux] Track all register cache validity in one place (#197113)

In this change I've expanded the existing RegisterSetType enum
to be used as part of a singular cache tracking object which replaces
all the separate booleans. These booleans were hard to track and 
set/reset in the right places.

This new validity object can be reset by default constructing,
and uses a member initialiser so everything starts out as invalid.

RegisterSetType is now a bitmask enum for easier storage.
It's 32-bit now which is enough for now. Just in case we expand it. 
(and I previously updated all sizeof calls to use RegisterSetType
instead of the raw type)

The SME and SME 2 entries have been renamed to ZA and ZT
as this is what ptrace calls them. Note that SME's pseudo registers
are still managed in their own unique way, I hope to address that
later.

[lldb][test][AArch64] Add test for AArch32 compatibility execution (#211793)

This should catch obvious problems like the one in #211692 in
future.

To run AArch32 programs on AArch64 you need a few things:
* Hardware that has AArch32 mode at EL0.
* A kernel built with CONFIG_COMPAT on.
* (usually) A bunch of 32-bit libraries installed.

We are dodging the 3rd one by compiling a standalone assembly
program that doesn't use any other libraries.

With clang being a cross-compiler and lld a cross-linker,
we should be able to do this without any 32-bit compatibility
libraries being installed.

To check for the first 2, we run that program normally.
If it fails to run, we don't have them. If it does run,

[AArch64][GlobalISel] Use integer type for cttz icmp type. (#212327)

[TableGen] don't print redundant diagnostic when parser sees Error token at end of file. (#212410)

Fixes #151476. 

Currently TableGen parser emits `error: Unexpected token at top level`
when it sees `tgtok::Error` token after failing to parse the object
list, even though that token's corresponding diagnostics were already
emitted during lexing. This change makes `ParseFile` return true when it
sees `tgtok::Error` at end of file, thereby avoiding the redundant
diagnostic.

[ORC] Fix buildSimpleReexportsAliasMap signature. (#212420)
