[InstCombine] fix wrong undef handling when converting select to shuffle As discussed in: https://bugs.llvm.org/show_bug.cgi?id=32486 ...the canonicalization of vector select to shufflevector does not hold up when undef elements are present in the condition vector. Try to make the undef handling clear in the code and the LangRef.
