Resubmit^2: [JumpThreading] Thread jumps through two basic blocks

This reverts commit 41784bed01543315a1d03141e6ddc023fd914c0b.

Since the original revision ead815924e6ebeaf02c31c37ebf7a560b5fdf67b,
this revision fixes three issues:

- This revision fixes the Windows build.  My original patch improperly
  copied EH pads on Windows.  This patch disregards jump threading
  opportunities having to do with EH pads.

- This revision fixes jump threading to a wrong destination.
  Specifically, my original patch treated any Constant other than 0 as 1
  while evaluating the branch condition.  This bug led to treating
  constant expressions like:

    icmp ugt i8* null, inttoptr (i64 4 to i8*)

  to "true".  This patch fixes the bug by calling isOneValue.

- This revision fixes the cost calculation of two basic blocks being
  threaded through.  Note that getJumpThreadDuplicationCost returns
  "(unsigned)~0" for those basic blocks that cannot be duplicated.  If
  we sum of two return values from getJumpThreadDuplicationCost, we
  could have an unsigned overflow like:

    (unsigned)~0 + 5 = 4

  and mistakenly determine that it's safe and profitable to proceed
  with the jump threading opportunity.  The patch fixes the bug by
  checking each return value before summing them up.

[JumpThreading] Thread jumps through two basic blocks

Summary:
This patch teaches JumpThreading.cpp to thread through two basic
blocks like:

  bb3:
    %var = phi i32* [ null, %bb1 ], [ @a, %bb2 ]
    %tobool = icmp eq i32 %cond, 0
    br i1 %tobool, label %bb4, label ...

  bb4:
    %cmp = icmp eq i32* %var, null
    br i1 %cmp, label bb5, label bb6

by duplicating basic blocks like bb3 above.  Once we duplicate bb3 as
bb3.dup and redirect edge bb2->bb3 to bb2->bb3.dup, we have:

  bb3:
    %var = phi i32* [ @a, %bb2 ]
    %tobool = icmp eq i32 %cond, 0
    br i1 %tobool, label %bb4, label ...

  bb3.dup:
    %var = phi i32* [ null, %bb1 ]
    %tobool = icmp eq i32 %cond, 0
    br i1 %tobool, label %bb4, label ...

  bb4:
    %cmp = icmp eq i32* %var, null
    br i1 %cmp, label bb5, label bb6

Then the existing code in JumpThreading.cpp can thread edge
bb3.dup->bb4 through bb4 and eventually create bb3.dup->bb5.

Summary:
Currently type test assume sequences inserted for devirtualization are
removed during WPD. This patch delays their removal until later in the
optimization pipeline. This is an enabler for upcoming enhancements to
indirect call promotion, for example streamlined promotion guard
sequences that compare against vtable address instead of the target
function, when there are small number of possible vtables (either
determined via WPD or by in-progress type profiling). We need the type
tests to correlate the callsites with the address point offset needed in
the compare sequence, and optionally to associated type summary info
computed during WPD.

This depends on work in D71913 to enable invocation of LowerTypeTests to
drop type test assume sequences, which will now be invoked following ICP
in the ThinLTO post-LTO link pipelines, and also after the existing
export phase LowerTypeTests invocation in regular LTO (which is already
after ICP). We cannot simply move the existing import phase
LowerTypeTests pass later in the ThinLTO post link pipelines, as the
comment in PassBuilder.cpp notes (it must run early because when
performing CFI other passes may disturb the sequences it looks for).

This necessitated adding a new type test resolution "Unknown" that we
can use on the type test assume sequences previously removed by WPD,
that we now want LTT to ignore.

Depends on D71913.

[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;

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.

Revert "[WebAssembly][InstrEmitter] Foundation for multivalue call lowering"

Summary:
This reverts commit 3ef169e586f4d14efe690c23c878d5aa92a80eb5. The
purpose of this commit was to allow stack machines to perform
instruction selection for instructions with variadic defs. However,
MachineInstrs fundamentally cannot support variadic defs right now, so
this change does not turn out to be useful.

Depends on D73927.

SIP process check, and an attempt at checking if developer mode is

AMDGPU: Correct memory size for image intrinsics

This was incorrectly rounding up to the next power of 2. v4f32 was
rounding up to v8f32, which was just wrong. There are also v3i16/v3f16
available in MVT, so we don't even need to round the f16 cases
anymore. Additionally, this field is really an EVT so we don't even
need to consider this.

Also switch some asserts to return invalid. We should have an IR
verifier for these intrinsic return types, but for now it's better to
not assert on IR that passes the verifier.

This should also probably be fixed to consider that dmask is really
eliminating some of the loaded components.

[lldb/Reproducers] Change the way we instrument void* arguments

The reproducer instrumentation cannot automatically serialize and
deserialize void* arguments. Currently we deal with this by explicitly
preventing these methods from being instrumented. This has the undesired
side effect of breaking replay when that method returns a value later
used by another SB API call.

The solution is to change our approach and instrument these methods.
Instead of using the DUMMY macro, we just make (de)serialization of the
void pointer a NOOP and always return a nullptr.
