Ryan Macnak c2058b0f40 [vm, compiler] Allocate only one SSA index to definitions, even those with pair representation. ...

Change the mapping between SSA indices and virtual registers from 1:1 to 1:2.

This shrinks the size of bit vectors used during optimizations, and leaves the size of bit vectors used during register allocation the same.
