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.

keep f32 in SSE registers and f64 in x87.  This

Change addLegalFPImmediate to permit float and
double variants to do different things.

Make APInt::dump() public, remove newline, use it to
dump ConstantSDNode's.
