[PATCH][GOLD] Make relocation stub order independent of Unordered_map implementation.


Hi,

    This patch changes the way relocations stub offsets are assigned
so that the offsets are independent of the implementation of
Unordered_map.  It also move code to initialize
Stringpool_template::offset_ to make
Stringpool_template::new_key_offset() doing less work.   This was
tested on both x86_64 and ARM Linux.

        * arm.cc (Stub_table::Stub_table): Initialize new data members
        Stub_table::reloc_stubs_size_ and Stub_table::reloc_stubs_addralign_.
        (Stub_table::add_reloc_stub): Assign stub offset and update
        Stub_table::reloc_stubs_size_ and Stub_table::reloc_stubs_addralign_.
        (Stub_table::reloc_stubs_size_, Stub_table::reloc_stubs_addralign_):
        New data members.
        (Stub_table::update_data_size_and_addralign): Use
        Stub_table::reloc_stubs_size_ and Stub_table::reloc_stubs_addralign_
        instead of going over all reloc stubs.
        (Stub_table::finalize_stubs): Do not assign reloc stub offsets.
        * stringpool.cc (Stringpool_template::Stringpool_template): Initialize
        Stringpool_template::offset_ depending on
        Stringpool_template::zero_null_.
        (Stringpool_template::new_key_offset): Remove code to initialize
        Stringpool_template::offset_.
        * stringpool.h (Stringpool_template::set_no_zero_null): Set
        Stringpool_template::offset_ to zero.
