AMDGPU/GlobalISel: Don't use legal v2s16 G_BUILD_VECTOR
If we have s_pack_* instructions, legalize this to
G_BUILD_VECTOR_TRUNC from s32 elements. This is closer to how how the
s_pack_* instructions really behave.
If we don't have s_pack_ instructions, expand this by creating a merge
to s32 and bitcasting. This expands to the expected bit operations. I
think this eventually should go in a new bitcast legalize action type
in LegalizerHelper.
We already directly emit the shift operations in RegBankSelect for the
vector case. This could possibly be cleaned up, but I also may want to
defer doing this expansion to selection anyway. I'll see about that
when I try to actually match VOP3P instructions.
This breaks the selection of the build_vector since tablegen doesn't
know how to match G_BUILD_VECTOR_TRUNC yet, so just xfail it for now.

[MCA] Remove verification check on MayLoad and MayStore. NFCI
Field NumMicroOpcodes is currently used by mca to model the number of uOPs
dispatched from the uOp-Queue to the out of order backend. From a 'dispatch'
point of view, an instruction with zero opcodes is still valid; it simply
doesn't consume any dispatch group slots.
However, mca doesn't expect an instruction with zero uOPs to consume pipeline
resources because it is seen as a contradiction. In practice, it only makes
sense if such an instruction is eliminated and never really executed. It may be
that mca is being too conservative here. However I believe that mca is right,
and we should probably check that inconsistency in CodeGenSchedule.cpp (when we
also verify scheduling classes in general).
This patch removes the check for MayLoad and MayStore in mca. That check is
probably too conservative: we are already checking if a zero-uops instruction
consumes any processor resources. Note also that instructions with unmodelled
side-effects also tend to set the MayLoad/MayStore flags even if - theoretically
speaking - they might not even consume any hw resources in practice.
In future we may want to implement different checks (possibly outside of mca)
and potentially revisit the logic in mca that verifies instructions.
For that reason I have raised PR44797.

[lldb] Ignore type sugar in TypeSystemClang::GetPointerType
Summary:
Currently having a typedef for ObjC types is breaking member access in LLDB:
```
typedef NSString Str;
NSString *s; s.length; // OK
Str *s; s.length; // Causes: member reference base type 'Str *' (aka 'NSString *') is not a structure or union
```
This works for NSString as there the type building from `NSString` -> `NSString *` will correctly
build a ObjCObjectPointerType (which is necessary to make member access with a dot possible),
but for the typedef the `Str` -> `Str *` conversion will produce an incorrect PointerType. The reason
for this is that our check in TypeSystemClang::GetPointerType is not desugaring the base type,
which causes that `Str` is not recognised as a type to a `ObjCInterface` as the check only sees the
typedef sugar that was put around it. This causes that we fall back to constructing a PointerType
instead which does not allow member access with the dot operator.
This patch just changes the check to look at the desugared type instead.

Recommit: DebugInfo: Check DW_OP_convert in loclists with Split DWARF
Originally committed in:

Reverted in:
f75301d16d444d8cb6810d679290df744bc79ec7
Reverted because it was running llc directly (rather than %llc_dwarf)
which uses COFF files on Windows which LLVM doesn't support all DWARF
features in.
This functionality isn't fully working, but sets up the testing for a
follow-on patch that demonstrates and fixes the brokenness related to
DWO ID hashing this construct.

Pretty printing the return value, although a good idea in theory, turned
out to be more confusing than anything else because they require

This changes the logging to behave more like how deserialization is
traced, although a bit more verbose because some of the serializers are
are calling each other.

[X86] Add custom lowering for lrint/llrint to either cvtss2si/cvtsd2si or fist.
lrint/llrint are defined as rounding using the current rounding
mode. Numbers that can't be converted raise FE_INVALID and an
implementation defined value is returned. They may also write to
errno.
I believe this means we can use cvtss2si/cvtsd2si or fist to
convert as long as -fno-math-errno is passed on the command line.
Clang will leave them as libcalls if errno is enabled so they
won't become ISD::LRINT/LLRINT in SelectionDAG.
For 64-bit results on a 32-bit target we can't use cvtss2si/cvtsd2si
but we can use fist since it can write to a 64-bit memory location.
Though maybe we could consider using vcvtps2qq/vcvtpd2qq on avx512dq
targets?
gcc also does this optimization.
I think we might be able to do this with STRICT_LRINT/LLRINT as
well, but I've left that for future work.

[SEH] Remove CATCHPAD SDNode and X86::EH_RESTORE MachineInstr
The CATCHPAD node mostly existed to be selected into the EH_RESTORE
instruction, which sets the frame back up when 32-bit Windows exceptions
return to the parent function. However, creating this MachineInstr early
increases the risk that other passes will come along and insert
instructions that use the stack before ESP and EBP are restored. That
happened in PR44697.
Instead of representing these in the instruction stream early, delay it
until PEI. Mark the blocks where this needs to happen as EHPads, but not
funclet entry blocks. Passes after PEI have to be careful not to hoist
instructions that can use stack across frame setup instructions, so this
should be relatively reliable.
