[WebAssembly] Refactor atomic operation definitions (NFC)
Summary: - Make `ATOMIC_I`, `ATOMIC_NRI`, `AtomicLoad`, `AtomicStore` classes and make other operations inherit from them - Factor the common opcode prefix '0xfe' out from the opcodes into the common class - Reorder instructions in the order of increasing opcodes Reviewers: tlively Subscribers: dschuff, sbc100, jgravelle-google, sunfish, jfb, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D58338 llvm-svn: 354421
