[PATCH] D122757: [InstCombine] Fold (ctpop(X) == N) || (X != 0) into X != 0 where N > 0

- Move change and its test to InstSimplify

- Remove tests whose and/or are replaced with select

This is because InstSimlify/and-or-icmp-* tests does not include such tests, and as far as I tried on goldbot.org simplifyAndOrOfICmps* functions in InstructionSimplify.cpp does not acknowledge select operands to optimize.
