[PATCH][GOLD] Classes to support stub generation in ARM.

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

Hi,

    This patch contains a number of classes to support stub generation
of ARM.  Since the stub machinery is pretty self-contained, it is
broken out to make reviewing easier.  The code to use these classes
will be sent out in subsequent patches.
