Tim Northover 33fe993f2e Atomics: make use of the "cmpxchg weak" instruction.
This also simplifies the IR we create slightly: instead of working out
where success & failure should go manually, it turns out we can just
always jump to a success/failure block created for the purpose. Later
phases will sort out the mess without much difficulty.
