Simon Atanasyan e13a9624c2 [ELFYAML] Provide explicit value for relocation addendums in the test
The `Addend` is an optional field of the `Relocation` YAML record. But
we do not provide its default value while reading it from a YAML file
and so it might keep uninitialized.

I am going to fix the code by a separate commit. We might either make
this field mandatory (at least for .rela sections) or specify 0 as
a default value explicitly.

Simon Atanasyan 5d19c67a68 [ELFYAML] Support mips64 relocation record format in yaml2obj/obj2yaml
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.

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.
