Cache the Function dependent subtarget on the MachineFunction.
As preparation for removing the getSubtargetImpl() call from
TargetMachine go ahead and flip the switch on caching the function
dependent subtarget and remove the bare getSubtargetImpl call
from the X86 port. As part of this add a few tests that show we
can generate code and assemble on X86 based on features/cpu on
the Function.
