6a32adc4e5 - Handle special scalar_to_vector case: splats. Using a native 128-bit 
shuffle before inserting on a 256-bit vector.
- Add AVX versions of movd/movq instructions
- Introduce a few COPY patterns to match insert_subvector instructions.
This turns a trivial insert_subvector instruction into a register copy,
coalescing the xmm into a ymm and avoid emiting on more instruction.

580f4a9c1c ARM assembly parsing and encoding for SSAT instruction. 
Fix the Rn register encoding for both SSAT and USAT. Update the parsing of the
shift operand to correctly handle the allowed shift types and immediate ranges
and issue meaningful diagnostics when an illegal value or shift type is
specified. Add aliases to parse an ommitted shift operand (default value of
'lsl #0').

Add tests for diagnostics and proper encoding.

093b8cabbc Check in updated CMake dependencies after Evan's latest round of 
refactorings. Several places that shouldn't have dependend on Target no
longer do. Also almost all of the CodeGen dependencies have gone away
for the MCDisassembler. Others add reasonable dependencies within the
target-specific layers.

8bcf9496d0 Add a missing enumerator to this switch. Currently its in the 
assert-path code, as previously we would have fallen off the end of the
function, but please review and let me know if this should go somewhere
else.

This fixes a Clang warning:

e4616ace02 Simply ARM so_reg MIOperandInfo definitions. 
The shift immediate encoding, printing, etc. is handled directly by the
enclosing operand definition, so it should be a vanilla immediate, not a
nested complex operand (shift_imm).
