members cannot have defaulted comparisons.

I'm not sure why this is using the raw enum value. This makes reading
the generated table comprehensible.

Several of these other functions are probably also convergent, but
these two seem obviously convergent.

Most of the functions emitted here should probably be convergent, but
only barriers are currently marked. Introduce this helper before
adding convergent to more functions.

[X86] Use 64-bit version of source register in LowerPATCHABLE_EVENT_CALL and LowerPATCHABLE_TYPED_EVENT_CALL

Summary:
The PATCHABLE_EVENT_CALL uses i32 in the intrinsic. This
results in the register allocator picking a 32-bit register. We
need to use the 64-bit register when forming the MOV64rr
instructions. Otherwise we print illegal assembly in the text
output.

I think prior to this it was impossible for SrcReg to be equal
to DstReg so the NOP code was not reachable.

While there use Register instead of unsigned.

Also add a FIXME for what looks like a bug.

Summary:
Move breakpoints from the old, bad ArgInfo::count to the new, better
ArgInfo::max_positional_args.   Soon ArgInfo::count will be no more.

This functionality is tested in `TestFormatters.py`, `TestDataFormatterSynthVal.py`,
`TestDataFormatterSynthType.py`.

You may notice that the old code was passing 0 arguments when count was 1, and passing
1 argument when count is 2.

This is no longer necessary because max_positional_args counts the self pointer
correctly.

Remove the explicit move enabling NVRO.

Do not add user-site packages directory to the python search path.
This avoids test failures if there's an incompatible lit module installed
inside the user-site packages directory, as it gets prioritized over the lit
from the PYTHONPATH.

The actual bug was fixed in commit d052a578.

I've tried to maintain test intent for AArch64 and WebAssembly
by replacing undef index operands with something else.

[LegalizeTypes] When promoting BITREVERSE/BSWAP don't take the shift amount into account when determining the shift amount VT.

If the target's preferred shift amount VT can't hold any shift
amount for the promoted VT, we should use i32. The specific shift
amount shouldn't matter. The type will be adjusted later when the
shift itself is type legalized. This avoids an assert in getNode.

Fixes PR43820.

[TargetLowering] Add getBooleanContents contents check to "SETCC (SETCC), [0|1], [EQ|NE]  -> SETCC" combine.

This combine is only valid if the inner setcc produces a 0/1 result
or the inner type is MVT::i1.

I haven't seen this cause any issues, just happened to notice it
while reviewing combines in this function.

While there also fix another call to use the value type from the
SDValue for the operand instead of calling SDNode::getValueType(0).
Though its likely the use is result 0, its not guaranteed.

Summary:
[nfc][libomptarget] Decrease coupling between files

debug.h used the symbol omptarget_device_environment so implicitly required
an include of omptarget-nvptx.h to compile. Similarly interface.h uses size_t.

Moving this declaration to a new header means cancel, critical can now build
without omptarget-nvptx.h. After this change, debug.h, cancel.cu, critical.cu
could move under a common source directory.

[nfc][libomptarget] Inline option into target_impl

Subset of D69423. The macros that were in option.h are all target dependent.
Inlining the header simplifies the dependency graph when looking to move code

Summary:
We don't pattern match pairwise shuffles in SelectionDAG. So we
should only return the optimized costs if its not a pairwise
shuffle.

I think SLP vectorizer gives priority to non pairwise shuffle if
the cost is the same. And the look up for reduction intrinsics
passes false for the pairwise flag. So this probably has no real
effect today.

PTEST and especially the MOVMSK instructions are slow on Knights Landing
or later. As a bonus, this patch increases instruction parallelism by
emitting:
    KORTEST(PCMPNEQ(a, b), PCMPNEQ(c, d)) == 0
Instead of:
    KORTEST(AND(PCMPEQ(a, b), PCMPEQ(c, d))) == ~0

The error message says to add the #include.

Using 'auto' when the type is not obvious is undesired.

(it is just a test commit actually)

I've accidentally reverted one of my previous patches.
It was not catched by bots because (I guess) they do not
build in debug (we have a test case which triggers an assert
in MSVS when runs without this change).

Reported by Jordan Rupprecht.

There is a minor flaw in the implementation of function lowerPhis.
This function replaces values of regclass Vreg_1 (boolean values)
involved in PHIs into an SGPR. Currently it iterates over the MBBs
and performs an inplace lowering of PHIs and fails to lower any
incoming value that itself is another PHI of Vreg_1 regclass.
The failure occurs only when the MBB where the incoming PHI value
belongs is not visited/lowered yet.

To fix this problem, collect all Vreg_1 PHIs upfront and then
perform the lowering.

Pass SymbolStringPtr by const-ref to avoid copies (which require atomic
ref-count operations).

This reverts commit dd501045.

This is useful for the property databases we want to add for abstract
serialization, since root classes can have interesting properties.

Using `?` as an optional marker is very useful in Clang's AST-node
emitters because otherwise we need a separate class just to encode
the presence or absence of a base node reference.
