Fix CU relative vs. absolute DIE offsets.
	* dwarf2loc.h (dwarf2_fetch_die_location_block): Rename parameter
	offset to offset_in_cu.
	* dwarf2read.c (process_enumeration_scope): Add CU offset to
	TYPE_OFFSET.
	(dwarf2_fetch_die_location_block): Rename parameter offset to
	offset_in_cu.  New variable offset, add CU offset to OFFSET_IN_CU.
