2098cb1e6f ARM refactor am6offset usage for VLD1. 
Split am6offset into fixed and register offset variants so the instruction
encodings are explicit rather than relying an a magic reg0 marker.
Needed to being able to parse these.

295b1e84ce Fix a NEON disassembly case that was broken in the recent refactorings. As more of this code gets refactored, a lot of these manual decoding hooks should get smaller and/or go away entirely.

94e6643fce The different flavors of ARM have different valid subsets of registers. Check 
that the set of callee-saved registers is correct for the specific platform.

2f2e3c4737 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.

03a173eb71 Don't automatically set the "fc" bits on MSR instructions if the user didn't ask for them. This is a divergence from gas' behavior, but it is correct per the documentation and allows us to forge ahead with roundtrip testing.

2d768fd379 Use literal pool loads instead of MOVW/MOVT for materializing global addresses when optimizing for size. 
On spec/gcc, this caused a codesize improvement of ~1.9% for ARM mode and ~4.9% for Thumb(2) mode. This is
codesize including literal pools.

The pools themselves doubled in size for ARM mode and quintupled for Thumb mode, leaving suggestion that there
is still perhaps redundancy in LLVM's use of constant pools that could be decreased by sharing entries.

Fixes PR11087.

617075fcf6 A landing pad could have more than one predecessor. In that case, we want that 
predecessor to remove the jump to it as well. Delay clearing the 'landing pad'
flag until after the jumps have been removed. (There is an implicit assumption
in several modules that an MBB which jumps to a landing pad has only two
successors.)
