[InstCombine] Add tests for cases where we don't recognize type promoted rotate idioms. These rotates take the form (x << (n & mask)) | (x >> (-n & mask)) where mask is bitwidth - 1. If x has been promoted to a wider type than its original bit width due to type promotion we fail to narrower it and therefore don't recognize it as a rotate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@332068 91177308-0d34-0410-b5e6-96231b3b80d8
