This needs to be done + before register allocation to be efficient, because it may duplicate basic + blocks and WebAssembly performs register allocation at a whole-function + level. Note that LLVM's GPU code has such a pass, but it linearizes control + flow (e.g. both sides of branches execute and are masked) which is undesirable + for WebAssembly. +* Basic relooper to expose control flow as an AST. +* Figure out how to properly use MC for virtual ISAs.
