Log:
claim that "st" is from the 80-bit register file.  This causes x87-using inline
asm to die with:

ScheduleDAG.cpp:269: failed assertion `false && "Couldn't find the register class"'

instead of:
failed assertion `RegMap->getRegClass(VReg) == RC && "Register class of operand and regclass of use don't agree!"'

yay.
