* h8300-tdep.c: Multiarch. Drop `set machine' command in favor of

`set architecture'.  Unify naming convention of functions.
	(h8300_skip_prologue): Improve prologue analysis.
	(h8300_push_arguments): Rewritten to more closely match GCC's
	bizarre argument-passing behavior, along with the comment describing
	said behavior.
	* remote-hms.c (hms_regnames): Don't use NUM_REGS in definition.
	* config/h8300/tm-h8300.h: Multiarch.  Just keep stuff needed by
	sim, remote-e7000.c, remote-hms.c and remote.c
