LoongArch: Allow using bstrins for masking the address in atomic_test_and_set
We can use bstrins for masking the address here. As people are already
working on LA32R (which lacks bstrins instructions), for future-proofing
we check whether (const_int -4) is an and_operand and force it into an
register if not.
gcc/ChangeLog:
* config/loongarch/sync.md (atomic_test_and_set): Use bstrins
for masking the address if possible.
