280dfad489 ARM VLD parsing and encoding. 
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.

81b2928d80 ARM addrmode5 represents the 'U' bit of the encoding backwards. 
The disassembler needs to use the AM5 factory methods instead of just
building up the immediate directly.

9e5887b17e 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)

4ebbf7b8a8 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.
