3228 branch relaxation. If generating a normal insn, and there
3229 is not enough room in the current frag, call relax_close_frag()
3230 to close it. Update mips_relax.sizes[]. Emit fixups for the
3231 second version of a relaxable macro. Record the first relaxable
3232 fixup in mips_relax. Remove tc_gen_reloc workaround.

3243 first version is needed.
3244 (tc_gen_reloc): Remove relaxation handling.
3245 (md_convert_frag): Go through the fixups for a relaxable macro and
3246 mark those that belong to the unneeded alternative as done. If the
3247 second alternative is needed, adjust the fixup addresses to account
3248 for the deleted first alternative.
