Two types of instructions have register lists:
* LDM, et al, uses a bit mask to indicate the register list.
* VLDM, et al, uses a base register plus number.
The LDM instructions may be non-contiguous, but the VLDM ones must be
contiguous. Those are semantic checks that should be done later in the
compiler. Also postpone the creation of the bit mask until it's needed.
