[PATCH] D18155: Instcombine: try to avoid wasted work in ConstantFold

I know I'm a bit late here, but wondering if you have any IR / test case which can be used for perf testing? I've created D75634 <https://reviews.llvm.org/D75634> as a different approach to this issue, but don't have a test case for this myself.
