Davide Italiano 6e7a212748 [NewGVN] Fix verification of MemoryPhis in verifyMemoryCongruency(). ...

verifyMemoryCongruency() filters out trivially dead MemoryDef(s),
as we find them immediately dead, before moving from TOP to a new
congruence class.
This fixes the same problem for PHI(s) skipping MemoryPhis if all
the operands are dead.
