Chris Lattner 2ee743b53b only try to fold constantexpr operands when the worklist is first populated,
don't bother every time going around the main worklist.  This speeds up a 
release-asserts opt -std-compile-opts on 403.gcc by about 4% (1.5s).  It
seems to speed up the most expensive instances of instcombine by ~10%.
