The sh4 passes floating point arguments in FP registers.

Elena, let me withdraw this patch -- I've got one that supercedes it.

	* sh-tdep.h (struct gdbarch_tdep): New member FLOAT_ARGLAST_REG.
	* sh-tdep.c (sh_gdbarch_init): For sh4, set FLOAT_ARG0_REGNUM
	and FLOAT_ARGLAST_REGNUM, to be used for argument passing.
	(sh_push_dummy_call): Use the above to pass floating point
	arguments in floating point registers when called for.
