AtomicExpand: Allow incrementally legalizing atomicrmw (#103371)

Browse Source 
If a lowering changed control flow, resume the legalization
loop at the first newly inserted block.

This will allow incrementally legalizing atomicrmw and cmpxchg.

The AArch64 test might be a bugfix. Previously it would lower
the vector FP case as a cmpxchg loop, but cmpxchgs get lowered
but previously weren't. Maybe it shouldn't be reporting cmpxchg
for the expand type in the first place though.
