0f63075613 Proper encoding for VLDM and VSTM instructions. The register lists for these 
instructions have to distinguish between lists of single- and double-precision
registers in order for the ASM matcher to do a proper job. In all other
respects, a list of single- or double-precision registers are the same as a list
of GPR registers.

60f4870c22 Covert VORRIMM to be produced via early target-specific DAG combining, rather than legalization. 
This is both the conceptually correct place for it, as well as allowing it to be more aggressive.

d966817f3c Add support for code generation of the one register with immediate form of vorr. 
We could be more aggressive about making this work for a larger range of constants,
but this seems like a good start.

7a25825033 Unlike a lot of NEON instructions, vext isn't _actually_ parameterized by element size. Instead, 
all of the different element sizes are pseudo instructions that map down to vext.8 underneath, with
the immediate shifted left to reflect the increased element size.

92b5a2eb16 The MC code couldn't handle ARM LDR instructions with negative offsets: 
vldr.64 d1, [r0, #-32]

The problem was with how the addressing mode 5 encodes the offsets. This change
makes sure that the way offsets are handled in addressing mode 5 is consistent
throughout the MC code. It involves re-refactoring the "getAddrModeImmOpValue"
method into an "Imm12" and "addressing mode 5" version. But not to worry! The
majority of the duplicated code has been unified.

5df0e0a61d Rename getAddrModeImm12OpValue to getAddrModeImmOpValue and expand it to work 
with immediates up to 16-bits in size. The same logic is applied to other LDR
encodings, e.g. VLDR, but which use a different immediate bit width (8-bits in
VLDR's case). Removing the "12" allows it to be more generic.
