Robin Morisset c2d1634d13 Refactor AtomicExpandPass and add a generic isAtomic() method to Instruction ... Summary: Split shouldExpandAtomicInIR() into different versions for Stores/Loads/RMWs/CmpXchgs. Makes runOnFunction cleaner (no more redundant checking/casting), and will help moving the X86 backend to this pass. This requires a way of easily detecting which instructions are atomic. I followed the pattern of mayReadFromMemory, mayWriteOrReadMemory, etc.. in making isAtomic() a method of Instruction implemented by a switch on the opcodes.
