ARM: Better disassembly for pc-relative LDR.
...
When the operand is a plain immediate rather than a label, print it
as [pc, #imm] like we do for the Thumb2 wide encoding variant.

ARM assembly aliases for add negative immediates using sub.

'add r2, #-1024' should just use 'sub r2, #1024 ' rather than erroring out.
Thumb1 aliases for adding a negative immediate to the stack pointer,
also.
