Initial implementation of 'fence' instruction, the new C++0x-style replacement for llvm.memory.barrier.

This is just a LangRef entry and reading/writing/memory representation; optimizer+codegen support coming soon.

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.

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.

   - buildPieces was return a C++ object from inside an extern "C". (MSVC didn't like that)
   - clang_getCursorReferenceNameRange was missing a CINDEX_LINKAGE causing a link error.

Addresses PR10466, although the crash from that PR only triggers in cases where DAGCombine misses optimizing a shuffle.

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.

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:

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).
