[PATCH][GOLD] Tune stub group size.

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

Hi,

    This patch changes the default stub group size, which was
originally copied from the ARM back-end in bfd.  Gold is slightly less
efficient in sharing stubs.  The ARM back-end in bfd uses a different
type of stub than requested if the existing stub is compatible.  Gold
right now cannot do that, so we need to reserve more space.  I also
restrict the stub group size to be less than 1M when fixing the
cortex-A8 workaround since this is the branch range for long
conditional branch.

        * arm.cc (Target_arm::do_relax): Reserve more space for stubs.
        Restrict stub-group size to be within long conditional branch
        range when working around cortex-A8 erratum.
