Craig Topper a171a5eb84 [InstCombine] Don't let folding (select (icmp eq (and X, C1), 0), Y, (or Y, C2)) create more instructions than it removes 
Summary:
Previously this folding had no checks to see if it was going to result in less instructions. This was pointed out during the review of D34184

This patch adds code to count how many instructions its going to create vs how many its going to remove so we can make a proper decision.

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.
