f4ca84a7ab ARM NEON relax parse time diagnostics for alignment specifiers.
There's more variation that we need to handle. Error checking will need
to be on operand predicates.

2f57374e32 Darwin assembler improved relocs when w/o subsections_via_symbols.
When the file isn't being built with subsections-via-symbols, symbol
differences involving non-local symbols can be resolved more aggressively.
Needed for gas compatibility.

633ce3426c Move target-specific logic out of generic MCAssembler.
Whether a fixup needs relaxation for the associated instruction is a
target-specific function, as the FIXME indicated. Create a hook for that
and use it.

fe71651f99 Simple branch relaxation for Thumb2 Bcc instructions.
Not right yet, as the rules for when to relax in the MCAssembler aren't
(yet) correct for ARM. This is a step in the proper direction, though.

fe5f0cfa29 Generalize the fixup info for ARM mode.
We don't (yet) have the granularity in the fixups to be specific about which
bitranges are affected. That's a future cleanup, but we're not there yet.

2b239cbcf6 Sink codegen optimization level into MCCodeGenInfo along side relocation model
and code model. This eliminates the need to pass OptLevel flag all over the
place and makes it possible for any codegen pass to use this information.

5b31ef50f5 ARM Fixup valus for movt/movw are for the whole value.
Remove an assert that was expecting only the relevant 16bit portion for
the fixup being handled. Also kill some dead code in the T2 portion.

d94ffffc87 ARM fix encoding of VMOV.f32 and VMOV.f64 immediates.
Encode the immediate into its 8-bit form as part of isel rather than later,
which simplifies things for mapping the encoding bits, allows the removal
of the custom disassembler decoding hook, makes the operand printer trivial,
and prepares things more cleanly for handling these in the asm parser.

c4fcff419c Check in a patch that has already been code reviewed by Owen that I'd forgotten to commit.
Build on previous patches to successfully distinguish between an M-series and A/R-series MSR and MRS instruction. These take different mask names and have a *slightly* different opcode format.

Add decoder and disassembler tests.

Improvement on the previous patch - successfully distinguish between valid v6m and v7m masks (one is a subset of the other). The patch had to be edited slightly to apply to ToT.
