aarch64: Tweak atomic-inst-cas.c options
atomic-inst-cas.c has code to skip __atomic_compare_exchange_n
calls for invalid memory orderings, but -Winvalid-memory-model
applies before the dead code is removed (which is the right
behaviour IMO). This patch therefore suppresses the warning
for this test.
gcc/testsuite/
* gcc.target/aarch64/atomic-inst-cas.c: Add
-Wno-invalid-memory-model.
