Jakob Stoklund Olesen 0488d6ee5d Handle sub-register operands in recomputeRegClass().
Now that getMatchingSuperRegClass() returns accurate results, it can be
used to compute constraints imposed by instructions using a sub-register
of a virtual register.

This means we can recompute the register class of any virtual register
by combining the constraints from all its uses.
