 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
