The cpymemdi/setmemdi implementation doesn't fully support strict alignment.
Block the expansion if the alignment is less than 16 with STRICT_ALIGNMENT.
Clean up the condition when to use MOPS. (PR103100)
The original patch for GCC 12 removed MOPS & SIMD conditionals for setmem and
cpymem expansions in aarch64.md file. However, this version for GCC 11 does not
backport the SIMD & MOPS-related changes and retains the conditions in aarch64.md
file to preserve correctness and compatibility with the GCC 11 backend.
All changes and outputs have been verified by the author.
