History
Chris Lattner e2cc1ad230 don't bother calling ConstantFoldInstruction unless there is a use of the 
instruction (which disqualifies stores, unreachable, etc) and at least the
first operand is a constant.  This filters out a lot of obvious cases that
can't be folded.  Also, switch the IRBuilder to a TargetFolder, which tries
harder.
