<br>
MIPS64 ELF file has a very specific relocation record format. Each record might specify up to three relocation operations. So the `r_info` field in fact consists of three relocation type sub-fields and optional code of "special" symbols.<br>

The patch implements support of the MIPS64 relocation record format in yaml2obj/obj2yaml tools by introducing new optional Relocation fields: `Type2`, `Type3`, and `SpecSym`. These fields are recognized only if the object/YAML file relates to the MIPS64 target.<br>
