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.

Fix various typos in comments.

Remove xfail for PR/56839 now that it is fixed.

Fix include.

Move two functions from atomic_init_testset.c
sync_val_compare_and_swap_1 --> atomic_cas_8_cas.c
sync_val_compare_and_swap_2 --> atomic_cas_16_cas.c
this helps with pullups
