    Properly handle 64-bit GOT relocations

    This patch fixes 2 issues:

    1. Since the GOT offset is always negative, we need to use signed int
    to support 64-bit GOT relocations.
    2. R_X86_64_PLTOFF64 uses the address of GLOBAL_OFFSET_TABLE, which is
    the address of the .got.plt section, not the .got section.

        PR gold/16945
        * x86_64.cc (Target_x86_64::Relocate::relocate): Use signed int
        for got_offset.  Properly get GOT address for R_X86_64_PLTOFF64.
