ARM

ARM should be relatively straightforward:

You'll need to move the shifting into parse_gpr() and parse_vr() in dasm_arm.lua. These should use waction() to emit a (new) VREG op for dynamic registers. The VREG op needs to know the shift amounts for merging the register number. Note that FPRs require an extra bit at a different shift position.
