Rui Ueyama a3635b7b3b [PECOFF][Writer] Fixed a bug that an empty section is emit to the section header.

Rui Ueyama cf68e2a1b1 [PECOFF][Writer] Compute the size of a chunk each time it's added rather than all at once.
Contents of ".reloc" section depends on the addresses of other sections, so
the section cannot be created until all the other sections are created and get
their memory addresses (RVAs). That means that computation of section size
needs to be at least two pass.

Techynically there's no reason to compute it all at once, but instead we can
compute the address of a section as added to the output file. Doing so helps
us to create ".reloc" section.

Rui Ueyama 18c67a158b [PECOFF][Writer] Separate AtomChunk from SectionChunk.
The optional data directory header contains addresses to some atoms such
as the import address table in data section. Such fields can naturally
be set by relocation if we make the optional data driectory as an atom.

Currently we assume that atoms are always in a section, so we can't create
a file header with atoms. This patch separates section chunk from atom
chunk, to allow atom-based file header.

Rui Ueyama 8d10164326 [lld][PECOFF] Support IMAGE_REL_I386_DIR32 relocation.
With this patch, it can now resolve relocations in the same output file.
"Hello world" program does not still work because call to the DLL routine
is not supported yet.

Rui Ueyama ef2c5413a9 [lld][PECOFF] Read relocation entries.
Summary:
COFFReference class is defined to represent relocation information for
COFFDefinedAtom, as ELFReference for ELFDefinedAtom. ReaderCOFF can now
read relocation entries and create COFFReferences accordingly.

I need to make WriterPECOFF to handle the relocation references created by
the reader, but this patch is already big, so I think it's probably better
to get it reviewed now.

Rui Ueyama 8d6151fd29 [PECOFF][Writer] Implement the writer that can emit text section.
lld can now output a valid Windows executable with a text section that does nothing
but just returns immediately. It's not able to handle relocations, symbol tables,
data sections, etc, so it still can't do anything practical, though.

Rui Ueyama 9e56839a83 [lld][PECOFF] Add WinLinkDriver and PECOFFTargetInfo.
Add WinLinkDriver and connect it to the existing COFF reader. Remaining
parts are still stubs, so while it can now read a COFF file, it still
cannot link or output PE/COFF files yet.

Michael J. Spencer 64afcb4c6b Move everything over to TargetInfo.
I really would have liked to split this patch up, but it would greatly
complicate the lld-core and lld drivers having to deal with both
{Reader,Writer}Option and TargetInfo.

Nick Kledzik abb6981f68 Major refactoring: Remove Platform concept. In its place there are
now Reader and Writer subclasses for each file format.  Each Reader and
Writer subclass defines an "options" class which controls how that Reader
or Writer operates.
