Jakob Stoklund Olesen 3c4d54c4bd Implement value affinities for register allocation. ...

An SSA value is usually biased towards a specific register class or a
stack slot, depending on the constraints of the instructions using it.

Represent this bias as an Affinity enum, and implement a merging
algorithm for updating an affinity to satisfy a new constraint.

Affinities will be computed as part of the liveness analysis. This is
not implemented yet.
