[PATCH 2/2] cleanup: constify argument passed to dwarf form predicates

[Sanimir Agovic]

Dwarf form predicate functions do not modify their argument and thus made
them const.

gdb:

2013-07-23  Sanimir Agovic  <sanimir.agovic@inte.com>

	dwarf2read.c (attr_form_is_block): Make argument const.
	(attr_form_is_section_offset): Make argument const.
	(attr_form_is_constant): Make argument const.
	(attr_form_is_ref): Make argument const.
