[GOLD][PATCH] Refactor THUMB branch encoding code to avoid code duplication.

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

Hi,
      This patch refactors code for handling THUMB long branch offset
encoding and decoding to avoid code duplication.  It also adds a
missing part of a previous patch for handling THUMB16_SPECIAL_TYPE in
Stub_template::Stub_template.
