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.

Michael J. Spencer 57752dc56e Factor File::addAtom out to MutableFile::addAtom. 
This removes a bunch of llvm_unreachables and makes a File's mutability part of the type system.

Michael J. Spencer aedfa6a36b Fix MSVC compat. MSVC doesn't have bzero. 
Although the code is not valid to begin with. It is trying to do a raw memory
copy of a non standard-layout type. nameoffset is not guaranteed to directly
follow cmdsize.

This should be properly fixed.

Nick Kledzik 7145cf6846 Add 'invalid' as a Reference Kind so that unknown/invalid kind strings can return that fact to the caller for use in constructing an error message, rather that triggering an assertion.

Nick Kledzik 40b68559e8 Move implementation of WriterOptionsMachO to its own file. Reduced redundant 
ivars in WriterOptionsMachO instead have its methods compute ivar interactions.
Refactor mach-o Reference Kinds and introduce abstract class KindHandler.
Split up StubAtoms.hpp by architecture.  Add support for 32-bit x86 stubs.

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.
