[Bitcode] Fix bitcode compatibility issue with clang.arc.use intrinsic
Summary:
In r349534, objc arc implementation is switched to use intrinsics and at
the same time, clang.arc.use is renamed to llvm.objc.clang.arc.use to
make the naming more consistent. The side-effect of that is llvm no
longer recognize it as intrinsics and codegen external references to
it instead.
Rather than upgrade the old intrinsics name to the new one and wait for
the arc-contract pass to remove it, simply remove it in the bitcode
upgrader.

[CodeGen] Reuse BlockUtils for -unreachableblockelim pass (NFC)
Summary:
The logic in the -unreachableblockelim pass does the following:
1. It traverses the function it's given in depth-first order and
creates a set of basic blocks that are unreachable from the
function's entry node.
2. It iterates over each of those unreachable blocks and (1) removes any
successors' references to the dead block, and (2) replaces any uses of
instructions from the dead block with null.
The logic in (2) above is identical to what the `llvm::DeleteDeadBlocks`
function from `BasicBlockUtils.h` does. The only difference is that
`llvm::DeleteDeadBlocks` replaces uses of instructions from dead blocks
not with null, but with undef.
Replace the duplicate logic in the -unreachableblockelim pass with a
call to `llvm::DeleteDeadBlocks`. This results in less code but no
functional change (NFC).

[LSR] Attempt to increase the accuracy of LSR's setup cost
In some loops, we end up generating loop induction variables that look like:
{(-1 * (zext i16 (%i0 * %i1) to i32))<nsw>,+,1}
As opposed to the simpler:
{(zext i16 (%i0 * %i1) to i32),+,-1}
i.e we count up from -limit to 0, not the simpler counting down from limit to
0. This is because the scores, as LSR calculates them, are the same and the
second is filtered in place of the first. We end up with a redundant SUB from 0
in the code.
This patch tries to make the calculation of the setup cost a little more
thoroughly, recursing into the scev members to better approximate the setup
required. The cost function for comparing LSR costs is:
return std::tie(C1.NumRegs, C1.AddRecCost, C1.NumIVMuls, C1.NumBaseAdds,
C1.ScaleCost, C1.ImmCost, C1.SetupCost) <
std::tie(C2.NumRegs, C2.AddRecCost, C2.NumIVMuls, C2.NumBaseAdds,
C2.ScaleCost, C2.ImmCost, C2.SetupCost);

different.

When comparing a symbolic region and a constant, the constant would be

widen/truncate the constant to the width of the symbol expression's

AMDGPU: Handle "uniform-work-group-size" attribute (fix for RADV)
A previous patch for "uniform-work-group-size" attribute was found to break
some RADV and possibly radeon SI tests and had to be retracted.
This patch fixes that.

Avoid using -S in combination with "script"; it's unreliable.

Relax testcase.
Recent versions of llvm monorepo builds build libc++abi.dylib as libc++abi.1.dylib.
This accespts both variants.

[Reproducers] Add tests for different types of functionality
This patch adds test that check that functionality in lldb continues to
work when replaying a reproducer.
- Entries in image list are identical.
- That stepping behaves the same.
- That the data formatters behave the same.

Remove the warning in
DynamicLoaderDarwinKernel::KextImageInfo::LoadImageUsingMemoryModule
which would list every kext that failed to load when doing kernel
debugging. Instead, in DynamicLoaderDarwinKernel::ParseKextSummaries,
print a summary of how many kexts lldb was unable to load at the end.
I want to reduce the amount of output at the start of kernel debug
sessions a bit; we'll see if anyone really wanted to see the list of
which kexts specifically were unable to be loaded.
No functional change, only changing lldb's output at the start of
a kernel debug session.

[LoopRotate] fix crash encountered with callbr
Summary:
While implementing inlining support for callbr
(https://bugs.llvm.org/show_bug.cgi?id=40722), I hit a crash in Loop
Rotation when trying to build the entire x86 Linux kernel
(drivers/char/random.c). This is a small fix up to r353563.
Test case is drivers/char/random.c (with callbr's inlined), then ran
through creduce, then `opt -opt-bisect-limit=<limit>`, then bugpoint.
Thanks to Craig Topper for immediately spotting the fix, and teaching me
how to fish.
