[lldb] Fix TestSBValueSetTypeSyntheticOverride with libstdc++ (#210495)

My test added in #209056 assumed that a `CXXSyntheticChildren`
implementation for `std::vector` is readily available on all platforms,
that is not the case.

Do the simplest thing and remove this part of the test for now.

[mlir][bufferization] Avoid invalid memref.cast in to_buffer folding (#208973)

Fixes #202782

When folding bufferization.to_buffer(bufferization.to_tensor(...)), only
create a memref.cast if the source and destination memref types are
cast-compatible.

This avoids asserting on unranked memrefs with different memory spaces
and leaves the original bufferization ops in place instead.

[AArch64][PAC] Rework the expansion of AUT/AUTPAC pseudos (#169699)

Refactor `AArch64AsmPrinter::emitPtrauthAuthResign` to improve
readability and tune the conditions when `emitPtrauthDiscriminator` is
allowed to clobber address discriminator operands.

When resigning, do not clobber address discriminator register used for
authentication if it is also used for signing. Such clobbering would
prevent passing raw, 64-bit value as the new discriminator. Clarify
other corner cases of clobbering address discriminator operands.

Reuse `enum PtrauthCheckMode` instead of separate `ShouldCheck` and
`ShouldTrap` flags and drop its `Default` enumerator.

[Clang][Interpreter] Respect default setting on Windows

MSCV does not support the -fPIC option. When it is passed, Clang falls
back to PIC level 2 on x86_64 and to a static binary on AArch64. Without
-fPIC, however, PIC is already enabled by default on both targets.

As a result, the PCH (built with the default PIC level by toolchain
hint) and the clang-repl instance (using the fallback PIC level) end up
with different PIC settings, consuming a mismatch.

Avoid passing -fPIC when targeting MSVC on Windows. This preserve the
existing semantics, since PIC is already enabled by default, while
ensuring that both the PCH and clang-repl use the same PIC level.
