4132 alternative of a relaxable macro. Remove redundant check for
4133 branch relaxation. If generating a normal insn, and there
4134 is not enough room in the current frag, call relax_close_frag()
4135 to close it. Update mips_relax.sizes[]. Emit fixups for the
4136 second version of a relaxable macro. Record the first relaxable
4137 fixup in mips_relax. Remove tc_gen_reloc workaround.

4148 first version is needed.
4149 (tc_gen_reloc): Remove relaxation handling.
4150 (md_convert_frag): Go through the fixups for a relaxable macro and
4151 mark those that belong to the unneeded alternative as done. If the
4152 second alternative is needed, adjust the fixup addresses to account
4153 for the deleted first alternative.
