[PATCH] Fix early late DWARF generation

[Richard Biener]

This fixes a recent regression where we generate symbolic locations while
early DWARF is still in effect.

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to trunk.

Richard.

	* dwarf2out.c (gen_remaining_tmpl_value_param_die_attributes):
	Only add locations in late dwarf.
	(gen_scheduled_generic_parms_dies): Do not set early dwarf here.
	(dwarf2out_early_finish): But do it here.
