[libcxx] [test] Fix filesystem permission tests for windows

On Windows, the permission bits are mapped down to essentially only
two possible states; readonly or readwrite. Normalize the checked
permission bitmask to match what the implementation will return.

[mlir][ODS]: Add per-op cppNamespace.

This is useful for dialects that have logical subparts.

[ArgumentPromotion] Fix byval alignment handling.

Make sure the alignment of the generated operations matches the
alignment of the byval argument.  Previously, we were just ignoring
alignment and getting lucky.

While I'm here, also delete the unnecessary "tail" handling.
Passing a pointer to a byval argument to a "tail" call is UB, so
rewriting to an alloca doesn't require any special handling.

[RISCV] Prefer to lower MC_GlobalAddress operands to .Lfoo$local

Similar to X86 D73230 and AArch64 D101872

With this change, we can set dso_local in clang's -fpic -fno-semantic-interposition mode,
for default visibility external linkage non-ifunc-non-COMDAT definitions.

For such dso_local definitions, variable access/taking the address of a
function/calling a function will go through a local alias to avoid GOT/PLT.
