re PR target/12916 (No vector ABI)

	PR target/12916
	* config/sparc/sparc.h (NPARM_REGS): Delete.
	(BASE_RETURN_VALUE_REG): Likewise.
	(BASE_OUTGOING_VALUE_REG): Likewise.
	(BASE_PASSING_ARG_REG): Likewise.
	(BASE_INCOMING_ARG_REG): Likewise.
	* config/sparc/sparc.c (sparc_strict_argument_naming): Test
	TARGET_ARCH64, not TARGET_V9.
	(function_arg_slotno): Dispatch based on the mode class.
	Handle vector modes like floating-point modes.
	(function_arg_record_value_1): Handle vector types like
	floating-point types.
	(function_arg_record_value_2): Likewise.
	Calculate regno after mode transformation.
	(function_arg): Handle vector modes like floating-point modes.
	(function_arg_partial_nregs): Replace NPARM_REGS by SPARC_INT_ARG_MAX.
	If ARCH64, do not recheck alignment.
	(function_arg_pass_by_reference): Reorder the conditions.
	(sparc_return_in_memory): Move after function_arg_padding.
	Implement calling conventions for vector modes.
	(sparc_struct_value_rtx): Move after sparc_return_in_memory.
	(function_value): Move scope of 'regbase'.
	Implement calling conventions for vector modes.
	(sparc_builtin_saveregs): Replace NPARM_REGS by SPARC_INT_ARG_MAX
	and BASE_INCOMING_ARG_REG by SPARC_INCOMING_INT_ARG_FIRST.
	(sparc_va_arg): Use function_arg_pass_by_reference to test whether
	the argument is passed by reference.
	(sparc_type_code): Handle vector types.
