There's no point calling for_each_rtx/FOR_EACH_SUBRTX on a LABEL_REF

gcc/
	* varasm.c (compute_reloc_for_rtx_1): Take a const_rtx.  Remove the
	pointer to the cumulative reloc value and return the value for
	this reloc instead.
	(compute_reloc_for_rtx): Take a const_rtx.  Call
	compute_reloc_for_rtx_1 directly for SYMBOL_REF and LABEL_REF,
	avoiding any recursion.  Use FOR_EACH_SUBRTX rather than
	for_each_rtx for the CONST case.

OK.
