X86: expand atomics in IR instead of as MachineInstrs. The logic for expanding atomics that aren't natively supported in terms of cmpxchg loops is much simpler to express at the IR level. It also allows the normal optimisations and CodeGen improvements to help out with atomics, instead of using a limited set of possible instructions.. rdar://problem/13496295 llvm-svn: 212119 2014-07-02 02:53:31 +08:00			`; CHECK: movsbl`
