Rui Ueyama aa7b304ea7 Remove the Native file format.
The Native file format was designed to be the fastest on-memory or
on-disk file format for object files. The problem is that no one
is working on that. No LLVM tools can produce object files in
the Native, thus the feature of supporting the format is useless
in the linker.

This patch removes the Native file support. We can add it back
if we really want it in future.

Rui Ueyama 9aee050a0c Remove group-parent references.
Previously section groups are doubly linked to their children.
That is, an atom representing a group has group-child references
to its group contents, and content atoms also have group-parent
references to the group atom. That relationship was invariant;
if X has a group-child edge to Y, Y must have a group-parent
edge to X.

However we were not using group-parent references at all. The
resolver only needs group-child edges.

This patch simplifies the section group by removing the unused
reverse edge. No functionality change intended.

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.

Nick Kledzik bb963dfb7e Factor out core linking options from Platform in a new ResolverOptions
class.  Change Resolver to no longer use Platform.  Core linking
now issues errors directly.  We need to factor that out later.

Rework how Darwin executable writer finds "main" atom.  It now
adds to core linking an Atom  which has a Reference to "main".
