My problems with this patch, and with adding support for ternary ops
- it increases the size of MonoInst by 4/8 bytes.
- it slows down every phase of the JIT by changing linear code into loops,
ie. instead of
it is now a loop with an unknown upper bound.
All this to add support for exactly one rarely used instruction, CAS.
