Fix the issue that r143552 was trying to address the _right_ way. One-register lists are legal on LDM/STM instructions, but we should not print the PUSH/POP aliases when they appear. This fixes round tripping on this instruction.

Next step in the ongoing saga of NEON load/store assmebly parsing. Handle
VLD1 instructions that take a two-register register list.
Adjust the instruction definitions to only have the single encoded register
as an operand. The super-register from the pseudo is kept as an implicit def,
so passes which come after pseudo-expansion still know that the instruction
defines the other subregs.

Adding back support for printing operands symbolically to ARM's new disassembler
...
using llvm's public 'C' disassembler API now including annotations.
Hooked this up to Darwin's otool(1) so it can again print things like branch
targets for example this:
blx _puts
instead of this:
blx #-36
and includes support for annotations for branches to symbol stubs like:
bl 0x40 @ symbol stub for: _puts
and annotations for pc relative loads like this:
ldr r3, #8 @ literal pool for: Hello, world!
Also again can print the expression encoded in the Mach-O relocation entries for
things like this:
movt r0, :upper16:((_foo-_bar)+1234)

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.

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.
