Jakob Stoklund Olesen d9c1fa5205 Remove the TRI::getSubRegisterRegClass() hook.
This restores my karma after I added TRI::getSubClassWithSubReg().

Register constraints are applied 'backwards'.  Starting from the
register class required by an instruction operand, the correct question
is: 'How can I constrain the super-register register class so all its
sub-registers satisfy the instruction constraint?' The
getMatchingSuperRegClass() hook answers that.

We never need to go 'forwards': Starting from a super-register register
class, what register class are the sub-registers in?  The
getSubRegisterRegClass() hook did that.
