wattr_get is a macro, and the documentation states:

In practice, passing a variable there is harmless, except
that it is unused inside the macro, which causes unused

Summary:
Introduced OMPChildren class to handle all associated clauses, statement
and child expressions/statements. It allows to represent some directives
more correctly (like flush, depobj etc. with pseudo clauses, ordered
depend directives, which are standalone, and target data directives).
Also, it will make easier to avoid using of CapturedStmt in directives,
if required (atomic, tile etc. directives).
Also, it simplifies serialization/deserialization of the
executable/declarative directives.
Reduces number of allocation operations for mapper declarations.

We don't want mandatory events in the training log. We do want to handle
them, to keep the native size accounting accurate, but that's all.
Fixed the code, also expanded the test to capture this.

GNU ld allows sections after a non-SHF_ALLOC section to be covered by PT_LOAD
(PR37607) and assigns addresses to non-SHF_ALLOC output sections (similar to
SHF_ALLOC NOBITS sections. The location counter is not advanced).
This patch tries to fix PR37607 (remove a special case in
`Writer<ELFT>::createPhdrs`). To make the created PT_LOAD meaningful, we cannot
reset dot to 0 for a middle non-SHF_ALLOC output section. This results in
removal of two special cases in LinkerScript::assignOffsets. Non-SHF_ALLOC
non-orphan sections can have non-zero addresses like in GNU ld.
The zero address rule for non-SHF_ALLOC sections is weakened to apply to orphan
only. This results in a special case in createSection and findOrphanPos, respectively.

I skimmed the existing users of these matchers and don't see any problems
(eg, the caller assumes the matched value was a select instruction without checking).
So I think we can generalize the matching to allow the new intrinsics or the cmp+select idioms.
I did not find any unit tests for the matchers, so added some basics there. The instsimplify
tests are adapted from existing tests for the cmp+select pattern and cover the folds in
simplifyICmpWithMinMax().

If a function is in a unique section, putting all jump tables in
.rodata will prevent functions that have a jump table to get
garbage collect by the linker.
Therefore, we need to put jump table into a unique section as well.

Add `-fimplicit-none-type-always` to treat each specification-part
like it has `IMPLICIT NONE`. This is helpful for enforcing good Fortran
programming practices. We might consider something similar for
`IMPLICIT NONE(EXTERNAL)` as well.
Add `-fimplicit-none-type-never` to ignore occurrences of `IMPLICIT NONE`
and `IMPLICIT NONE(TYPE)`. This is to handle cases like the one below,
which violates the standard but it accepted by some compilers:
```
subroutine s(a, n)
implicit none
real :: a(n)
integer :: n
end
```

If we were to have an operation with an s16 def that needs to be
executed in a waterfall loop, not having s16 legal would place an
avoidable burden on RegBankSelect to widen it.
This was trying to constrain a physical register. By the verifier's
understanding, it's impossible to have a 1-bit copy to vcc/vcc_lo so
don't try to handle physregs.
This patch makes the 'Values' field optional. This is useful when we
handcraft the terminating entry of DIEs.

As noted on PR46885, the number of mask elements should always be a power of 2, so to fix the static analyzer warning we are better off replacing the condition to <= 4, and I've added a pow2 assertion as well.
We already need to include raw_ostream.h, also add missing StringRef.h and cstdint implicit dependencies.
Remove unnecessary includes from PDBExtras.cpp
Since we're messing with individual element loads we need to expose this to show whats going on.

This allows us to remove extra patterns from AArch64SVEInstrInfo.td

When any of the memrefs in a structured linalg op has a zero dimension, it becomes dead.
This is consistent with the fact that linalg ops deduce their loop bounds from their operands.
Note however that this is not the case for the `tensor<0xelt_type>` which is a special convention
that must be lowered away into either `memref<elt_type>` or just `elt_type` before this
canonicalization can kick in.

Before the patch `SATest compare`, produced quite obscure results
when something about the diagnostic have changed (i.e. its description
or the name of the corresponding checker) because it was simply two
lists of warnings, ADDED and REMOVED. It was up to the developer
to match those warnings, understand that they are essentially the
same, and figure out what caused the difference.
This patch introduces another category of results: MODIFIED.
It tries to match new warnings against the old ones and prints out
clues on what is different between two builds.
