This PR switches widened i64 add/sub lowering to use explicit
UADDO/USUBO carry
nodes instead of glue-based carry chains.

powerpc64le: switch long double to IEEE binary128
Change powerpc64le's long double from 64-bit double to IEEE 754
binary128 (quad, 113-bit mantissa), matching aarch64 and riscv64.
Gated on FreeBSD 16 and powerpc64le only.

[SPIR-V] Lower undef nested in a constant aggregate (#204377)
A constant aggregate whose element is itself an aggregate `undef` was
never lowered to a placeholder. The raw aggregate operand reached
IRTranslator on the llvm.spv.const.composite call and aborted with
"unable to translate instruction".
A similar issue was found and fixed during SPV_KHR_poison_freeze
implementation. So instead of re-inventing a wheel - unify lowering with
poison.
Addresses the following observation:

Pull exfat updates from Namjae Jeon:
- Convert exfat buffered and direct I/O to the iomap infrastructure
- Add the supporting block mapping changes needed for that conversion,
including multi-cluster allocation, byte-based cluster mapping
helpers
- Support SEEK_HOLE/SEEK_DATA and swapfile activation through iomap
- Fix damaged upcase-table handling so a zero-sized table does not lead
to an infinite loop
- Fix a potential use-after-free in exfat_find_dir_entry()
- Bound filename-entry advancement in exfat_find_dir_entry()
