[InstCombine] Add testcases for (mul (sext x), cst) --> (sext (mul x, cst')) and (mul (zext x), cst) --> (zext (mul x, cst')) for vectors constants. If the multiply won't overflow in the original type we can use a smaller mul and sign extend afterwards. We don't currently support this for vector constants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@341884 91177308-0d34-0410-b5e6-96231b3b80d8
