depend-cleanup.sh: rebuild strrchr.o on riscv64 if it came from strrchr.S
We have to switch back to the previous rule once the temporary
build fix has been replaced with a permanent fix.

msun: Fix up for recent rsqrt[fl] functions
Paul Zimmermann (of Core-Math and MPFR fame) graciously tested
the recently committed rsqrt[fl]() functions. He identified 127
incorrectly rounded values for rsqrtf() in round-to-nearest mode.
This patch fixes the rounding in RN. Exhaustive testing now shows
that rsqrtf() is corrected rounded for RN. He also tested rsqrt()
and rsqrtl() in the interval [1,4). Both appear to be correctly
rounded. Finally, the patch includes small changes to comments.
A concise list of changes is
* lib/msun/src/s_rsqrt.c:
. Fix comments.
* lib/msun/src/s_rsqrtf.c
. Fix comments.
. Exhaustive testing by Paul Zimmermann found 127 incorrectly
rounded values in round-to-nearests. These gave have the

libc/riscv64: temporarily unhook strrchr() from the build
A bug was discovered in the riscv64 assembly implementation of
this function. Fall back to the generic implementation until a
fix can be developed.

libc: Add free_sized() and free_aligned_sized() as per C23
Add C23 sized deallocation entry points as thin wrappers around free(3).
Implementations may ignore size and alignment hints, so behaviour stays
correct for existing allocations without validating caller metadata yet.
When jemalloc is updated to 5.3.1, rewire these to je_free_sized() and
je_free_aligned_sized() so deallocation can use the allocator's sized
deallocation (free_sized for fast paths and free_aligned_sized for
correct aligned hints.)
Please note this change satisfies the standard interface only. Both
functions should be delegated to jemalloc after the upgrade so callers
get the intended allocator behaviour; until then, hints are unused and
neither sized nor aligned-sized deallocation optimizations apply.

[NVPTX] pass variadics frame as local pointer (#201661)
Pass the pointer for variadics as a local (addrspace(5)) pointer. This
enables InferAddressSpace to convert loads of vaargs to local loads
(pipeline reordered to accomadate) and will also save a register in
short pointer mode. We leave vaListType as a generic pointer and cast
when expanding va_start to maintain backwards compatibility with IR
written expecting the va_list to be a generic pointer.

Proactively getting metadata for every visited instruction is expensive.
Therefore, only store the current instruction and get the metadata only
