This encompasses several changes which are all interconnected: - Use the MC framework for printing almost all instructions. - AsmStrings are now live. - This introduces an indirection between LLVM vregs and WebAssembly registers, and a new pass, WebAssemblyRegNumbering, for computing a basic the mapping. This addresses some basic issues with argument registers and unused registers. - The way ARGUMENT instructions are handled no longer generates redundant get_local+set_local for every argument. This also changes the assembly syntax somewhat; most notably, MC's printing use sigils on label names, so those are no longer present, and push/pop now have a sigil to keep them unambiguous. The usage of set_local/get_local/$push/$pop will continue to evolve significantly. This patch is just one step of a larger change. llvm-svn: 252858
