[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.

[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.

[PECOFF] Handle hint field in Hint/Name table in the import library.

A hint is an index of the export pointer table in a DLL, at which
PE/COFF loader starts looking for a symbol name. The import library
comes with hints and symbol pairs, and as long as hints are in sync
with the actual symbol table in DLL, the symbols will be resolved
quickly. So, we shouldn't ignore hints but propagate them to an output.

In order to support linking against DLL, the linker needs to create defined
atoms for jump tables and etc. Because such atoms are not read from a file,
they lack some information such as an ordinal. With this patch, COFFDefinedAtom
is split into two classes; one is the base class of all COFF defined atoms, and
another is a concrete class for atoms read from file. More classes inheriting
COFFBaseDefinedAtom will be added for jump tables and etc.
