[libcxx-commits] [libcxxabi] [libunwind] [NFCI][test][asm] Enable AT&T syntax explicitly (PR #166818)

[Raul Tambre via libcxx-commits]

https://github.com/tambry created https://github.com/llvm/llvm-project/pull/166818

Implementation files using the Intel syntax typically explicitly specify it. Do the same for the few files where applicable for AT&T.

This enables building LLVM with `-mllvm -x86-asm-syntax=intel` in one's Clang config files (i.e. a global preference for Intel syntax).
