[ARM] Precommit test for D101898

[tmatheson]

Minimize the CHECK lines in the test

[tmatheson]

Add tests for v8m.baseline

llvm/test/CodeGen/ARM/atomicrmw_exclusive_monitor_ints.ll

+; Test the instruction sequences produced by atomicrmw instructions. In
+; particular, ensure there are no stores/spills inserted between the exclusive
+; load and stores, which would invalidate the exclusive monitor.
