8d11c6349f ARM/Thumb2 'cmp rn, #imm' alias to cmn. 
When 'cmp rn #imm' doesn't match due to the immediate not being representable,
but 'cmn rn, #-imm' does match, use the latter in place of the former, as
it's equivalent.

f3aefb56de Handle expressions of the form _GLOBAL_OFFSET_TABLE_-symbol the same way gas 
does. The _GLOBAL_OFFSET_TABLE_ is still magical in that we get a R_386_GOTPC,
but it doesn't change the immediate in the same way as when the expression
has no right hand side symbol.

840bf7eda7 ARM assembly aliases for BIC<-->AND (immediate). 
When the immediate operand of an AND or BIC instruction isn't representable
in the immediate field of the instruction, but the bitwise negation of the
immediate is, assemble the instruction as the inverse operation instead
with the inverted immediate as the operand.

a4e3c7fc4b 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.
