Optimizer support for atomic instructions (#1094)
* Teach EffectAnalyzer not to reorder atomics wrt other memory operations.
* Teach EffectAnalyzer not to reorder host operations with memory operations
* Teach various passes about the operands of AtomicRMW and AtomicCmpxchg
* Factor out some functions in DeadCodeElimination and MergeBlocks
