[PATCH] D40721: [InstSimplify] Run constant folding if no other simplifications were possible

[Igor Laevsky via Phabricator via llvm-commits]

I had run CTMarks and I see total compile time slowdown of about 5% with various benchmarks regressed up to 10%. This does seem a lot especially considering unclear benefit from this change. I need to figure out better approach here.
