[SLP]Fix crash in getReorderingData on all-poison reuse-mask slice
When the reuse-shuffle mask is iterated in Sz-sized parts and a part is
entirely PoisonMaskElem, `Val` stays at PoisonMaskElem (-1) and the
subsequent `UsedVals.test(Val)` trips the SmallBitVector OOB assertion.
Bail out of reordering in that case.

[clang-format] Recognize more braced initializers (#192299)
new
```C++
a = {x * x, x * x};
```
old
```C++
a = {x * x, x *x};
```
Fixes #57442.
The patch makes the program treat a brace following an equal sign a
braced initializer.

[lldb-server] Implement support for MultiBreakpoint packet
This is fairly straightforward, thanks to the helper functions created
in the previous commit.

[flang][semantics][openacc] Allow collapse clauses on do concurrent (#192488)
This PR generalizes the semantic checking for collapse clauses to work
on `do concurrent` and fixes two bugs exposed along the way:
- The first was that `collapse (n)` where n < the number of nested loops
was giving an assertion violation.
- The second was do concurrent index variables were causing an assertion
violation because they hadn't been declared before looking them up.
The lowering is implemented as a TODO which will happen in a following
diff.
[lldbremote][NFC] Factor out code handling breakpoint packets (#192915)
This commit extracts the code handling breakpoint packets into a helper
function that can be used by a future implementation of the
MultiBreakpointPacket.
It is meant to be purely NFC.
There are two functions handling breakpoint packets (`handle_Z` and
`handle_z`) with a lot of repeated code. This commit did not attempt to
merge the two, as that would make the diff much larger due to subtle
differences in the error message produced by the two. The only
deduplication done is in the code processing a GDBStoppointType, where a
helper struct (`BreakpointKind`) and function
(`std::optional<BreakpointKind> getBreakpointKind(GDBStoppointType
stoppoint_type)`) was created.
The following PRs are related to the MultiBreakpoint feature:

[Clang] fix parser recovery for invalid static_assert string messages (#187859)
Fixes #187690
---
This PR fixes parser recovery for invalid `static_assert` declarations
with string literal messages. The parser now stops the message lookahead
on `;` and `eof`, so invalid inputs are diagnosed as parse errors.
[FunctionAttrs] Remove declaration check lines (NFC) (#194384)
These are annoying, because they get dropped by UTC. We're not
inferring attributes on declarations anyway.
[z/OS] Mark shtest-ulimit-nondarwin.py unsupported on zos. (#194016)
This PR marks llvm/utils/lit/tests/shtest-ulimit-nondarwin.py
unsupported on z/OS.
[Attributor] Support SPIR-V address spaces (#192725)
Right now Attributor assumes that if the the target is a GPU is can use
a single set of address space numerical values to determine the local
address space, but that's not true in general, so add SPIR-V support,
which uses different values.
This fixes an instruction incorrectly being marked as dead and optimized
out for an OpenMP SPIR-V offloading example.

[SystemZ] z/OS only accept C initialization (#194023)
The TLS support only accept compile constant expressions (both C and
C++) on z/OS. Add #if to skip these tests on z/OS.
[LiveDebugValues] Use std::sort for register sorting in collectIDsForRegs (#194339)
VarLocBasedLDV::collectIDsForRegs sorts a SmallVector<Register> using
array_pod_sort which is a thin wrapper around qsort. That shows up as a hotspot
in compile-time profiles under __GI___qsort_r.
Switching this to an explicit-comparator llvm::sort call, which takes the
std::sort path instead improves compile-time with no change to code-size.

[Clang][HLSL] Fix -Wunused-variable (#194374)
Inline the variable definition into the assert given it is side effect
free and the variable name does not make the code much more clear.
[offload] Fix use of AsyncInfoWrapper's finalize function (#194098)
The expected use is to forward the error from the asynchronous
operation's issuing (e.g., launchImpl) directly into the
AsyncInfoWrapper::finalize(). The check of the error is already
performed inside that function. No need to forward a dummy success error
code.
[llvm][lli] fix lli crash when run variable arguments function as a interpret (#173719)
Run `lli` comand with the flag `-force-interpreter=true` to execute LLVM
bitcode, if `lli` run `variable arguments` function in the bitcode, it
will crash.
Fix #173718
[AMDGPU][MC] Permit unneeded VOPD mov operands to be non-zero (#194060)
Use ? instead of 0 in the tablegen definitions for VOPD containing
v_mov. This enables the instruction to be disassembled regardless of
what bits are in those fields, which helps diagnose broken code.
Previously, the disassembler would reject these.
