Chris Lattner 6f2ab04e91 Fix a fairly major performance problem. If a PHI node had a constant as ...

an incoming value from a block, the selector would evaluate the constant
at the TOP of the block instead of at the end of the block.  This made the
live range for the constant span the entire block, increasing register
pressure needlessly.
