        * config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): Remove.
        * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of
        the first sequence, the size of the second sequence, and a flag
        that says whether we should warn.
        (RELAX_OLD, RELAX_NEW, RELAX_RELOC[123]): Delete.
        (RELAX_FIRST, RELAX_SECOND): New.
        (mips_relax): New variable.
        (relax_close_frag, relax_start, relax_switch, relax_end): New fns.
        (append_insn): Remove "place" argument.  Use mips_relax.sequence
        rather than "place" to check whether we're expanding the second
        alternative of a relaxable macro.  Remove redundant check for
        branch relaxation.  If generating a normal insn, and there
        is not enough room in the current frag, call relax_close_frag()
        to close it.  Update mips_relax.sizes[].  Emit fixups for the
        second version of a relaxable macro.  Record the first relaxable
        fixup in mips_relax.  Remove tc_gen_reloc workaround.
        (macro_build): Remove all uses of "place".  Use mips_relax.sequence
        in the same way as in append_insn.
        (mips16_macro_build): Remove "place" argument.
        (macro_build_lui): As for macro_build.  Don't drop the add_symbol
        when generating the second version of a relaxable macro.
        (load_got_offset, add_got_offset): New functions.
        (load_address, macro): Use new relaxation machinery.  Remove
        tc_gen_reloc workarounds.
        (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
        version of a relaxable macro is needed.  Return -RELAX_SECOND if the
        first version is needed.
        (tc_gen_reloc): Remove relaxation handling.
        (md_convert_frag): Go through the fixups for a relaxable macro and
        mark those that belong to the unneeded alternative as done.  If the
        second alternative is needed, adjust the fixup addresses to account
        for the deleted first alternative.
