Log Message:
PR/56839 GCC emits wrong codes for compare_and_swap_1 bultins on armv5 (el & eb)

There is mismatch in signedness of the GCC builtin __sync_* function arguments
and the _atomic_* functions so we cannot directly alias them. Instead write
the __sync_* functions with signed arguments and pass them the unsigned
_atomics_* functions.
