// If previousBlock is non-nil, it registers changes vs. that block's
// end state in state.changedVars. Note that previousBlock will often
// not be a predecessor.
//
// Note that mergePredecessors behaves slightly differently between
// first and subsequent calls for a block.  For the first call, the
// starting state is approximated by taking the state from the

// registers for allocation. This affinity helps eliminate moves that
// are required for phi implementations and helps generate allocations
// for 2-register architectures.

// Note: regalloc generates a not-quite-SSA output. If we have:
//

//                 x2 = StoreReg x
