* mn10300-tdep.c (mn10300_push_arguments): rewrote
also removed code elsewhere that made use of RP_REGNUM
* config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE
