59d5358068 arm_disasm: Remove unnecessary code
This part of disassembly only determines the opcode, there's no need for offset calculation here.

2182adff9e dyncom: Handle left-operand PC correctly for data-processing ops
This is considered deprecated in the ARM manual (using PC as an operand),
however, this is still able to be executed on the MPCore (which I'm quite
sure would be rare to begin with).

03213f893e dyncom: Remove unnecessary initialization code.
Targeting ARM version variants was only a thing on armemu.

The reset routine also does basically the same thing as NewState.

3257d797e1 dyncom: Remove unnecessary abort-related cruft
Both the MPCore and the ARM9 have the same data abort model (base restored), so differentiating isn't necessary.
