Summary: This prints assembly for int32 integer operations defined in WebAssemblyInstrInteger.td only, with major caveats: - The operation names are currently incorrect. - Other integer and floating-point types will be added later. - The printer isn't factored out to handle recursive AST code yet, since it can't even handle control flow anyways. - The assembly format isn't full s-expressions yet either, this will be added later. - This currently disables PrologEpilogCodeInserter as well as MachineCopyPropagation becasue they don't like virtual registers, which WebAssembly likes quite a bit. This will be fixed by factoring out NVPTX's change (currently a fork of PrologEpilogCodeInserter).
