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:
lib/MC/MCMachOStreamer.cpp:201:11: error: enumeration value 'MCSA_IndirectSymbol' not handled in switch [-Werror,-Wswitch-enum]

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).

Update the comment. This feature is available only on Darwin at the moment. Though it's not Darwin-specific.

Remove some inititalizers that are the same as the default, move defs next to
their (singular) uses and generally simplify some formatting of asm operand
definitions.

unwind encoding for that function. This simply crawls through the prolog looking
for machine instrs marked as "frame setup". It can calculate from these what the
compact unwind should look like.

This is currently disabled because of needed linker support. But initial tests
look good.

The .local, .hidden, .internal, and .protected are not legal for all supported
file formats (in particular, they're invalid for MachO). Move the parsing for
them into the ELF assembly parser since that's the format they're for.
Similarly, .weak is used by COFF and ELF, but not MachO, so move the parsing
to the COFF and ELF asm parsers. Previously, using any of these directives
on Darwin would result in an assertion failure in the parser; now we get
a diagnostic as we should.
