types.c (double, longdouble): Merge identical SH and ARM typedefs, and add POWERPC64.

Browse source 
* src/types.c (double, longdouble): Merge identical SH and ARM
	typedefs, and add POWERPC64.
	* src/powerpc/ffi.c (ffi_prep_args64): Correct next_arg calc for
	struct split over gpr and rest.
	(ffi_prep_cif_machdep): Correct intarg_count for structures.
	* src/powerpc/linux64.S (ffi_call_LINUX64): Fix gpr offsets.
