[InstCombine] add tests for (1 << x) & 1 --> zext(x == 0) ; NFC This fold hit the trifecta: 1. It was untested. 2. It oversteps (multiuse is not checked, so increases instruction count). 3. It is incomplete (doesn't work for vectors). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@308102 91177308-0d34-0410-b5e6-96231b3b80d8
