Subzero: Merge SpillVariable functionality directly into Variable. Specifically, this is the ability to link variable B to variable A, such that if neither A nor B get a register assignment, they share a stack slot. This CL just refactors and keeps basically the same functionality, in preparation for new work on variable splitting.
