mips.h (LIBCALL_VALUE, [...]): Remove macros.

Browse Source 
* config/mips/mips.h (LIBCALL_VALUE, FUNCTION_VALUE,
	FUNCTION_VALUE_REGNO_P): Remove macros.
        * config/mips/mips-protos.h (mips_function_value): Remove.
        * config/mips/mips.c (mips_function_value): Rename to...
	(mips_function_value_1): ... this. Make static.  Handle receiving
	the function type in 'fn_decl_or_type' argument.
	(mips_function_value, mips_libcall_value,
	mips_function_value_regno_p): New function.
	(TARGET_FUNCTION_VALUE, TARGET_LIBCALL_VALUE,
	TARGET_FUNCTION_VALUE_REGNO_P): Define.
