Modified Files:
        src/tests/lib/libc/atomic: t___sync_compare_and_swap.c

Log Message:
tests/lib/libc/atomic: Test subword compare-and-swap explicitly.

Make sure the sign doesn't bleed into an adjacent word.

We already had failing tests, but this should make the failures a
little more obvious and perhaps check for more adjacent problems.

PR port-arm/56839: GCC emits wrong codes for compare_and_swap_1
bultins on armv5 (el & eb)
