[PATCH][2/2] Make SCCVN use conditional equivalences

This brings FRE/PRE up to the same level as DOM in being able to remove redundant conditionals. It does so by inserting temporary conditional expressions proved to be true on single predecessor edges. I've had to do a lot of testcase adjustments, thus the patch is now re-bootstrapping / testing
