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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84170 91177308-0d34-0410-b5e6-96231b3b80d8		2009-10-15 04:13:44 +00:00
