nvptx: Add support for subword compare-and-swap
This adds support for __sync_val_compare_and_swap and
__sync_bool_compare_and_swap for 1-byte and 2-byte long
values, which are not natively supported on nvptx.
Build and reg-tested on nvptx.
Build and reg-tested libgomp on x86_64 with nvptx accelerator.
