If you only need special treatment for SHT_MIPS_REGINFO, then I would
recommend only creating a Mips_output_section for SHT_MIPS_REGINFO.  It
should probably be named Mips_reginfo_section or something like that.
For other section types just return a regular Output_section, probably
by simply calling this->Target::do_make_output_section.

You can't override set_final_data_size without also overriding do_write.
Look at, e.g., Output_compress_section for an example of an
Output_section which is not the simple concatenation of input sections.
