[PATCH][ARM] Handle --target1-abs, --target1-rel and --target2 options.

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

Hi,

    This patch adds handling of --target1-abs, --target2-rel and
--target2 options.  Previously we hard-coded the real relocation types
of R_ARM_TARGET1 and R_ARM_TARGET2.

        * arm.cc (Target_arm::Target_arm): Move method definition outside of
        class definition.  Add code to handle --target1-rel, --target1-abs
        and --target2= options.
        (Target_arm::get_reloc_reloc_type): Change method to be non-static
        and const.
        (Target_arm::target1_is_rel_, Target_arm::target2_reloc_): New data
        member declaration.
        (Target_arm::Scan::local, Target_arm::Scan::global,
        Target_arm::Relocate::relocate,
        Target_arm::Relocatable_size_for_reloc::get_size_for_reloc): Adjust
        call to Target_arm::get_real_reloc_type.
        (Target_arm::get_real_reloc_type): Use command line options to
        determine real types of R_ARM_TARGET1 and R_ARM_TARGET2.
        * options.h (--target1-rel, --target1-abs, --target2): New ARM-only
        options.
