Several places in AsmPrinter.cpp print comments describing MachineOperand registers using MCRegisterInfo, which uses MCOperand-oriented names. This doesn't work for targets that use virtual registers exclusively, as WebAssembly does, since virtual registers are represented and printed differently. This patch preserves what seems to be the spirit of r229978, avoiding the use of TM.getSubtargetImpl(), while still using MachineOperand-oriented printing for MachineOperands.
