5872174fd8 [obj2yaml/yaml2obj] Add SHT_GROUP support.
This adds section group support to the tools obj2yaml and yaml2obj.

602706ee58 [Object] Support reading 64-bit MIPS ELF archives
The 64-bit MIPS ELF archive file format is used by MIPS64 targets.
The main difference from a regular archive file is the symbol table format:
1. ar_name is equal to "/SYM64/"
2. number of symbols and offsets are 64-bit integers

http://techpubs.sgi.com/library/manuals/4000/007-4658-001/pdf/007-4658-001.pdf
Page 96

The patch allows reading of such archive files by llvm-nm, llvm-objdump
and other tools. But it does not support archive files with number of symbols
and/or offsets exceed 2^32. I think it is a rather rare case requires more
significant modification of `Archive` class code.

09a46075ee [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.

http://techpubs.sgi.com/library/manuals/4000/007-4658-001/pdf/007-4658-001.pdf
page 40

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.

4f20ed1c36 Don't lookup an object symbol name in the module.
Instead, walk the obj symbol list in parallel to find the GV. This shouldn't
change anything on ELF where global symbols are not mangled, but it is a step
toward supporting other object formats.

Gold itself is ELF only, but bfd ld supports COFF and the logic in the gold
plugin could be reused on lld.

a18e46cbc9 Object, COFF: Tighten the object file parser
We were a little lax in a few areas:
- We pretended that import libraries were like any old COFF file, they
  are not.  In fact, they aren't really COFF files at all, we should
  probably grow some specialized functionality to handle them smarter.
- Our symbol iterators were more than happy to attempt to go past the
  end of the symbol table if you had a symbol with a bad list of
  auxiliary symbols.

237544b16d obj2yaml, yaml2obj: Add support for COFF executables
In support of serializing executables, obj2yaml now records the virtual address
and size of sections.  It also serializes whatever we strictly need from
the PE header, it expects that it can reconstitute everything else via
inference.

yaml2obj can reconstitute a fully linked executable.

In order to get executables correctly serialized/deserialized, other
bugs were fixed as a circumstance.  We now properly respect file and
section alignments.  We also avoid writing out string tables unless they
are strictly necessary.

16d8031f94 MC, COFF: Use relocations for function references inside the section
Referencing one symbol from another in the same section does not
generally require a relocation.  However, the MS linker has a feature
called /INCREMENTAL which enables incremental links.  It achieves this
by creating thunks to the actual function and redirecting all
relocations to point to the thunk.

This breaks down with the old scheme if you have a function which
references, say, itself.  On x86_64, we would use %rip relative
addressing to reference the start of the function from out current
position.  This would lead to miscompiles because other references might
reference the thunk instead, breaking function pointer equality.

This fixes PR21520.
