two conversions which are coded for repeatedly in this module.
(remote_threads_extra_info, remote_wait, remote_async_wait,
store_register_using_P, remote_store_registers, remote_write_bytes,

given that the actual code for downloading through a parallel port
is not conditionalized.

* mn10300-tdep.c (set_movm_offsets): Use symbolic names for the
bits, not hex literals. Handle the `other', `exreg0', and

r6, and r7, not r2, r3, r4, and r5.
(saved_regs_size): New function.
(mn10300_frame_chain, mn10300_frame_saved_pc): Use it, instead
of computing the same thing inline, incorrectly.

determining corresponding sections and map file entries. Call
map_index_vs_section_name_okay() to do this instead.
