[PATCH][GOLD] Add Cortex-A8 stub class.

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

Hi,

    This patch mainly adds a class to represent Cortex-A8 stubs.  Rest
of the stub machinery was also changed a little.  The do_write method
in the Stub base class is no longer pure virtual.  I moved the
relevant code from Reloc_stub to the base class.  The code was
extended to handle a new conditional branch instruction template used
in one of the Cortex-A8 stub template.  Now both the Reloc_stub and
the Cortex_a8_stub classes share the stub-writing code in the base
class via inheritance.  I also found a bug in the
Stub_factory::Stub_factory due to a missing "static" storage class
specifier.
