Heejin Ahn 3e2cfa03da [WebAssembly] Enable atomic expansion for unsupported atomicrmws ...

Summary:
Wasm does not have direct counterparts to some of LLVM IR's atomicrmw
instructions (min, max, umin, umax, and nand). This enables atomic
expansion using cmpxchg instruction within a loop for those atomicrmw
instructions.
