Jim Grosbach d146a02c79 ARM assembly parsing and encoding for VLD2 with writeback.
Refactor the instructions into fixed writeback and register-stride
writeback variants to simplify the offset operand (no more optional
register operand using reg0). This is a simpler representation and allows
the assembly parser to more easily handle these instructions.

Add tests for the instruction variants now supported.

Jim Grosbach 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.
