2014-05-20Fix elimination of conditional expressions in registerizeHarder.Ryan Kelly
Previously, attempts to eliminate a side-effect-free conditional expression would corrupt internal block state, because the sub-nodes belong to a different block than the one containing the expression. This fixes the problem by not splitting side-effect free conditionals across multiple blocks.
