Juergen Ributzka 2c68cde701 [FastISel][AArch64] Fix shift lowering for i8 and i16 value types. 
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>.

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
