  Log Message:
  -----------
  [libc++] Simplify the definition of string::operator== (#95000)

Instead of hardcoding a loop for small strings, always call
char_traits::compare which ends up desugaring to __builtin_memcmp.

Note that the original code dates back 11 years, when we didn't lower to
intrinsics in `char_traits::compare`.

Fixes #94222
