25de138b06 * mn10200-tdep.c (mn10200_push_arguments): Stack only needs to

        * config/mn10200/tm-mn10200.h (EXTRACT_RETURN_VALUE): Abort for
        structures > 8 bytes (temporary).
        (STORE_RETURN_VALUE): Likewise.
        (CALL_DUMMY): No longer undefine.
        (USE_STRUCT_CONVENTION): Use for args > 8 bytes.

a698d0d06f * mn10200-tdep.c: Remove lots of debugging printfs, update/improve
comments, formatting, etc.  Plus other minor fixes for problems
        I found during my first pass over the mn10200 port.
        (mn10200_analyze_prologue): New function.
        (mn10200_frame_chain, mn10200_init_extra_frame_info): Use it.
        * config/mn10200/tm-mn10200.h: Lots of updates/improvements to
        comments, formatting, etc.  Minor fixes for problems I found during
        my first pass over the mn10200 port.
        (TARGET_*_BIT): Define appropriately for ints, long longs, doubles and
        pointers.
        (REGISTER_VIRTUAL_TYPE): Define as a long.
        (EXTRACT_RETURN_VALUE): Rework to deal with long ints living
        in register pairs.
        (STORE_RETURN_VALUE): Similarly.
Checking in my initial changes, prologue scanning, etc.

Start mn10200 gdb port by adding copies of mn10300
        target-specific files with all instances of mn10300 changed
        to mn10200 to start with.
        * mn10200-tdep.c: new
        * config/mn10200/tm-mn10200.h: new, REGISTER_SIZE is 24 bits not 32,
        SP_REGNUM and FP_REGNUM are different, also no lar or lir.
        * config/mn10200/mn10200.mt: new
