Subject: [PATCH 1/2] [Mips] Use AtomicExpandPass for subword atomics
MIPS duplicates subword atomic address and mask preparation already
provided by AtomicExpandPass. We referenced the RISC-V implementation
to move this work into the generic pass and simplify LL/SC expansion.
Lower byte and halfword atomic RMW and cmpxchg operations through masked
intrinsics so AtomicExpandPass prepares aligned addresses, endian-aware
shifts, masks and shifted operands. Reuse generic widening for bitwise
RMWs and cmpxchg expansion for operations without a native LL/SC lowering.
Select masked and fullword atomic pseudos with explicit early-clobber
scratch outputs. Share their late LL/SC expansion and remove the atomic
custom inserters and duplicate post-RA pseudos. Run expansion and the MIPS
finalization passes in addPreEmitPass2 to keep intervening machine passes
from inserting stores into LL/SC loops.
Preserve MIPS16 and R5900 libcall lowering, Add regression coverage for
masks, fences, endian and ABI variants, retry loops, and pass ordering.

Subject: [PATCH 2/2] [Mips] Fix atomic opcode initialization on Windows
Windows builds reject runtime opcode enum expressions in unsigned
aggregate initializers as narrowing conversions. Convert the selected
opcodes to unsigned locals before constructing AtomicOpcodes, preserving
the existing opcode selection.
