Instead of trying to move ARGUMENT instructions back up to the top after
they've been scheduled or sunk down, use a fake physical register to
create a liveness constraint that prevents ARGUMENT instructions from
moving down in the first place. This is still not entirely ideal, however
it is more robust than letting them move and moving them back.

This arranges the types in the LLVM instruction names in the same order that
they appear in the WebAssembly opcode names, and eliminates
double-underscores.

Mangling type information into MachineInstr opcode names was a temporary
measure, and it's starting to get hairy. At the same time, the MC instruction
printer wants to use AsmString strings for printing. This patch takes the
first step, starting the process of adding AsmStrings for instructions.

This is a temporary assembly syntax that will likely evolve along with
broader upcoming syntax changes.
