R600/SI: Fix bug in SIInstrInfo::legalizeOpWithMove()

We must constrain the destination register class of legalized operands
to a VGPR class or else the illegal operand may be folded back into
the instruction by the register coalescer.

This fixes a bug in add.ll that will be uncovered by future commits.
