	libffi/src/sparc: ffi.c v8.S v9.S 

Log message:
	* src/sparc/ffi.c (ffi_prep_args_v9): Shift the parameter array
	when the structure return address is passed in %o0.
	(ffi_V9_return_struct): Rename into ffi_v9_layout_struct.
	(ffi_v9_layout_struct): Align the field following a nested structure
	on a word boundary.  Use memmove instead of memcpy.
	(ffi_call): Update call to ffi_V9_return_struct.
	(ffi_prep_closure): Define 'ctx' only for V8.
	(ffi_closure_sparc_inner): Clone into ffi_closure_sparc_inner_v8
	and ffi_closure_sparc_inner_v9.
	(ffi_closure_sparc_inner_v8): Return long doubles by reference.
	Always skip the structure return address.  For structures and long
	doubles, copy the argument directly.
	(ffi_closure_sparc_inner_v9): Skip the structure return address only
	if required.  Shift the maximum floating-point slot accordingly.  For
	big structures, copy the argument directly; otherwise, left-justify the
	argument and call ffi_v9_layout_struct to lay out the structure on
	the stack.
	* src/sparc/v8.S: Undef STACKFRAME before defining it.
	(ffi_closure_v8): Pass the structure return address.  Update call to
	ffi_closure_sparc_inner_v8.  Short-circuit FFI_TYPE_INT handling.
	Skip the 'unimp' insn when returning long doubles and structures.
	* src/sparc/v9.S: Undef STACKFRAME before defining it.
	(ffi_closure_v9): Increase the frame size by 2 words.  Short-circuit
	FFI_TYPE_INT handling.  Load structures both in integers and
	floating-point registers on return.
	* README: Update status of the SPARC port.
