[NFC][TableGen] Minor code cleanup in RegisterInfoEmitter (#181479)

Minor cleanup in codegen for `getSubClassWithSubReg` and
`getSubRegisterClass`:
- Use `getMinimalTypeForRange` to determine the entry type for table.
- Extract common code for table lookup into a lambda.

[SLP]Do not increase depth for type-changing nodes and NotProfitableForVectorization removal

The patch changes the maximum tree size analysis. 1. Do not increase
depth for type changing nodes (like casts and compares), allowing more
deeper trees to be built. 2. Removes NotProfitableForVectorization
workaround, not needed anymore after throttling enabled

[SPIRV] Fix `SPIRVTypeInst` `DenseMapInfo` implementation

The previous `DenseMapInfo` implementation was wrong.

The new implementation relies completely on `DenseMapInfo<MachineInst*>`'s.
To do this, we use "tag dispatch" to call a special constructor only
accessible by `DenseMapInfo` that bypasses the assertion when building
the emtpy/tombstone keys.

Addresses review comments from
https://github.com/llvm/llvm-project/pull/180898#pullrequestreview-3791945590.
We don't need to recursively collect direct users of the header mask, we
can do that as a separate step so that the main worklist loop only
handles potentially reassociatable candidates.

Also add back mention of tail folding to comment and a TODO.

[SystemZ] Enable rematerialization for scalar loads (#179838)

We can avoid the unnecessary spill by marking loads as rematerializable
and just directly loading from where the argument was originally passed
on the stack. TargetTransformInfo::isReMaterializableImpl checks to make
sure that any loads are MI.isDereferenceableInvariantLoad(), so we
should be able to move the load down to the remat site.

[clang][ssaf] Fix building on gcc-7 and MinGW/Cygwin (#181812)

So we had two problems:
1) gcc-7 does not fully support C++17 mandatory NRVO, so we need
   an explicit std::move in return statements to workaround this.
2) MinGW/Cygwin is picky about extern templates; this actually bit me
   once, so I'll think about how to mitigate in long term, but for now
   just add the missing declarations.

[LoopInterchange] Update tests generated by UTC (NFC) (#181804)

Update the LoopInterchange tests that use UTC to generate assertions, in
order to avoid irrelevant changes during other developments. Most of the
changes are simply the result of re-running UTC, but this patch also
includes a few additional minor adjustments by hand:

- Rename IR value names to suppress warnings by UTC.
- Delete `NOTE: Assertions have been ...` from the test file that
actually doesn't use UTC.
- Delete unnecessary `-pass-remarks-missed=...`.
- Add a store instruction for an unused GEP result, which could
otherwise affect other developments.

[Offload][test] Use just-compiled lld and llvm-symbolizer (#181793)

In a bootstrapping build with LLVM_ENABLE_PROJECTS=lld, the lld
executable will be found in LLVM's bin/ directory. But `check-offload`
will currently ignore it because the JIT plugin will look for `lld` in
`$PATH`. Similarly, the sanitizer tests require llvm-symbolizer during
execution to FileCheck the expected stack trace.

Add the llvm tools directory to `$PATH` so tests can use lld and
llvm-symbolizer in it. It should be prefered over a system-installed
lld/llvm-symbolizer.

Fixes the JIT and sanitizer tests of
[openmp-offload-amdgpu-clang-flang](https://lab.llvm.org/staging/#/builders/105).
