This fixes a regression intruced by r198113. Revision r198113 introduced an algorithm that tries to fold a vector shift by immediate count into a build_vector if the input vector is a known vector of constants. However the algorithm only worked under the assumption that the input vector type and the shift type are exactly the same. This patch disables the folding of vector shift by immediate count if the input vector type and the shift value type are not the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199213 91177308-0d34-0410-b5e6-96231b3b80d8
