[libcxx-commits] [libcxx] [FIX] Fix the function 'isctype' failed in arm64-be (PR #72992)

[via libcxx-commits]

https://github.com/W-50243 created https://github.com/llvm/llvm-project/pull/72992

The function 'isctype' failes in arm64-be while succeeds in arm64-le 。This is because the function does not judge the big endian and small endian modes to distinguish the value of __regex_word.
