[LoopUnrollAndJam] Visit phi operand dependencies in post-order
Fixes https://github.com/llvm/llvm-project/issues/58565
The previous implementation visits operands in pre-order, but this does
not guarantee an instruction is visited before its uses. This can cause
instructions to be copied in the incorrect order. For example:
```
a = ...
b = add a, 1
c = add a, b
d = add b, a
```
Pre-order visits does not guarantee the order in which `a` and `b` are
visited. LoopUnrollAndJam may incorrectly insert `b` before `a`.
This patch implements post-order visits. By visiting dependencies first,
we guarantee that an instruction's dependencies are visited first.

Fix a phase-ordering problem in SimplifyCFG.
Switch simplification could sometimes fail to notice when an

downstream parts of SimplifyCFG expect tautological branches to
already have been eliminated. The missed handling in switch

[OpenMP][JIT] Introduce support for AMDGPU
To JIT kernels for AMDGPUs we need to provide the architecture, the
triple, and a post-link callback. The first two are simple, the last one
is a little more complicated since we need to invoke `lld`. There is
some library interface but for that we need the lld library, which is
not generally available, thus we go with the executable for now. In
either way we need to manifest the (amdgcn) object file and read the
output from another file. We should try to avoid that in the future.
The options for `lld` are copied from the way clang invokes it.

[InstCombine] don't let 'exact' inhibit demanded bits folds for udiv
We shouldn't penalize instructions that have extra flags.
Drop the poison-generating flags if needed instead of bailing out.
This makes canonicalization/optimization more uniform.
There is a chance that dropping flags will cause some
other transform to not fire, but we added a preliminary
patch to avoid that with:

[SelectionDAG][GlobalISel] Don't use UnsignedDivisionByConstantInfo for divisor of 1.
The magic algorithm sets IsAdd indication for division by 1 that
the caller had to ignore.
I considered folding the ignore into UnsignedDivisionByConstantInfo,
but we only allow 1 for vectors of mixed visiors. And really what we
want to end up with is undef. Currently, we get to undef via
DemandedElts optimizations using the select instruction. We could
directly emit undef.

[lld-macho][nfc] Re-enable previously disabled test.
This check was previous disabled because the test kept failing on ARM64. The output from reported failure message
gave the impression that the bundle was created as an x86-64 bundle but upon further inspection, I believe that's
a bug in llvm-otool where it prints both -h and -f for both input files on ARM64.
So the "fix" here is to rewrite the test to run the two otool commands separately but concatenate the
output into one file for checking.

[clang] Add the check of membership in decltype for the issue #58674#
Originally, the code would take a lookup result as a member in the
current scope and build a member expression accordingly, if the lookup
result was not an operand of the address operator, or it was a field
declaration. However, a field declaration may come from another class,
and cause the issue #58674.
Thus, this patch fixes the issue via checking where does the field
declaration comes from, and if it comes from another class, then marks
it as not member in the current scope. The parent scopes of the current
scope are also checked, as the current scope may be associated to a
lambda or friend declaration.

CoroFrame: Put escaped variables with multiple lifetimes on coroutine frame
The llvm.lifetime.start intrinsic guarantees that the address for a
given alloca is always the same. So variables with escaped addresses
