This fix changes the parameters #r and #s that are passed to the UBFM/SBFM instruction to get the zero/sign-extension for free. The original problem was that the shift left would use the 32-bit shift even for i8/i16 value types, which could leave the upper bits set with "garbage" values. The arithmetic shift right on the other side would use the wrong MSB as sign-bit to determine what bits to shift into the value. This fixes <rdar://problem/17907720>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214788 91177308-0d34-0410-b5e6-96231b3b80d8
