Stella Stamenova 7a8865cea8 [lldbsuite] Make the names of test classes unique
Summary:
If the names are not unique, the tests overwrite each other's results and logs. This also causes failures on platforms where the files are locked for writing.

The names of the class/test pairs *have to* always be unique. The easiest way to achieve that is to name each class differently (usually the same as the file name).

Vedant Kumar 15718a6190 [CodeExtractor] Erase debug intrinsics in outlined thunks (fix PR22900)
Variable updates within the outlined function are invisible to
debuggers. This could be improved by defining a DISubprogram for the
new function. For the moment, simply erase the debug intrinsics instead.

This fixes verifier failures about function-local metadata being used in
the wrong function, seen while testing the hot/cold splitting pass.

Sean Fertile 795cc9332b [PPC64] Add split - stack support.
This support is slightly different then the X86_64 implementation in that calls
to __morestack don't need to get rewritten to calls to __moresatck_non_split
when a split-stack caller calls a non-split-stack callee. Instead the size of
the stack frame requested by the caller is adjusted prior to the call to
__morestack. The size the stack-frame will be adjusted by is tune-able through a
new --split-stack-adjust-size option.

Artem Dergachev fcf107d411 [analyzer] Teach CallEvent about C++17 aligned operator new().
In C++17, when class C has large alignment value, a special case of
overload resolution rule kicks in for expression new C that causes the aligned
version of operator new() to be called. The aligned new has two arguments:
size and alignment. However, the new-expression has only one "argument":
the construct-expression for C(). This causes a false positive in
core.CallAndMessage's check for matching number of arguments and number
of parameters.

Update CXXAllocatorCall, which is a CallEvent sub-class for operator new calls
within new-expressions, so that the number of arguments always matched
the number of parameters.

We don't need a separate node for every symbol, because whenever the first
symbol leaks, a bug is emitted, the analysis is sinked, and the checker
callback immediately returns due to State variable turning into null,
so we never get to see the second leaking symbol.

Sam McCall 8dc9dbb61a [clangd] Minimal implementation of automatic static index (not enabled).
Summary:
See tinyurl.com/clangd-automatic-index for design and goals.

Lots of limitations to keep this patch smallish, TODOs everywhere:
 - no serialization to disk
 - no changes to dynamic index, which now has a much simpler job
 - no partitioning of symbols by file to avoid duplication of header symbols
 - no reindexing of edited files
 - only a single worker thread
 - compilation database is slurped synchronously (doesn't scale)
 - uses memindex, rebuilds after every file (should be dex, periodically)

It's not hooked up to ClangdServer/ClangdLSPServer yet: the layering
isn't clear (it should really be in ClangdServer, but ClangdLSPServer
has all the CDB interactions).

Simon Pilgrim 5abb607ebe [ARM][NEON] Improve vector popcnt lowering with PADDL (PR39281)
As I suggested on PR39281, this patch uses PADDL pairwise addition to widen from the vXi8 CTPOP result to the target vector type.

This is a blocker for moving more x86 code to generic vector CTPOP expansion (P32655 + D53258) - ARM's vXi64 CTPOP currently expands, which would generate a vXi64 MUL but ARM's custom lowering expands the general MUL case and vectors aren't well handled in LegalizeDAG - improving the CTPOP lowering was a lot easier than fixing the MUL lowering for this one case......

Chandler Carruth e303c87e19 [TI removal] Make `getTerminator()` return a generic `Instruction`.
This removes the primary remaining API producing `TerminatorInst` which
will reduce the rate at which code is introduced trying to use it and
generally make it much easier to remove the remaining APIs across the
codebase.

Also clean up some of the stragglers that the previous mechanical update
of variables missed.

Users of LLVM and out-of-tree code generally will need to update any
explicit variable types to handle this. Replacing `TerminatorInst` with
`Instruction` (or `auto`) almost always works. Most of these edits were
made in prior commits using the perl one-liner:
```
perl -i -ple 's/TerminatorInst(\b.* = .*getTerminator\(\))/Instruction\1/g'
```

This also my break some rare use cases where people overload for both
`Instruction` and `TerminatorInst`, but these should be easily fixed by
removing the `TerminatorInst` overload.

Chandler Carruth edb12a838a [TI removal] Make variables declared as `TerminatorInst` and initialized

This is the biggest remaining chunk of the usage of `getTerminator()`

Several files saw more extensive updates where this would cascade to
requiring API updates within the file to use `Instruction` instead of
`TerminatorInst`. All of these were trivial in nature (pervasively using
`Instruction` instead just worked).
