8a3d29cf10 Simplify this pass by using a depth-first iterator to ensure that all 
operands are visited before the instructions themselves.

d16ad3e43c Use getVRegDef() instead of def_iterator. This leads to fewer defs being added 
with 2-address instructions, for about a 3.5% speedup of StrongPHIElimination on
403.gcc.

StrongPHIElimination compile time on 403.gcc.
