[SPARC] Use AtomicExpandPass to expand AtomicRMW instructions. They were previously expanded to CAS loops in a custom isel expansion, but AtomicExpandPass knows how to do that generically. Testing is covered by the existing sparc atomics.ll testcases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@264771 91177308-0d34-0410-b5e6-96231b3b80d8
