[PATCH][GOLD] Add a new class Arm_exidx_input_section.

[=?big5?b?RG91ZyBLd2FuICjD9q62vHcp?= <dougkwan at google dot com>]

Hi,

    This patch adds a new class Arm_exidx_input_section for EXIDX
input sections in objects.   The objects are stored in an map so that
we can look them up quickly either by their section indexes or the
section indexes of their linked text sections.  This is a part of my
patch to support EXIDX output section.
