Sam Parker 12b4374cd5 [AArch64] Port atomic rmw to ISLE (#4021) 
Also fix and extend the current implementation:
- AtomicRMWOp::Clr != AtomicRmwOp::And, as the input needs to be
  inverted first.
- Inputs to the cmp for the RMWLoop case are sign-extended when
  needed.
- Lower Xchg to Swp.
- Lower Sub to Add with a negated input.
- Added more runtests.
