[Doug Evans <dje at google dot com>]

Hi.
This is just a minor simplification.
Committed.

2013-04-15  Doug Evans  <dje@google.com>

	* dwarf2read.c (create_debug_types_hash_table): Use hex_string
	instead of phex.
	(lookup_dwo_unit, create_dwo_debug_info_hash_table_reader): Ditto.
	(create_dwo_in_dwp): Ditto.
