[optimizing compiler] Add support for volatile

- for backends: arm, x86, x86_64
- added necessary instructions to assemblies
- clean up code gen for field set/get
- fixed InstructionDataEquals for some instructions
- fixed comments in compiler_enums

* 003-opcode test verifies basic volatile functionality

  * The current recipe is as follows:
  * -# Use AnyStore ~= (LoadStore | StoreStore) ~= release barrier before volatile store.
  * -# Use AnyAny barrier after volatile store.  (StoreLoad is as expensive.)
- * -# Use LoadAny barrier ~= (LoadLoad | LoadStore) ~= acquire barrierafter each volatile load.

  * -# Use NTStoreStore to order non-temporal stores with respect to all later
