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 20e652d627 Add way to represent static archives in yaml test cases. 
Add SharedLibraryFile and ArchiveLibraryFile subclasses of File.

Add command line options to lld-core to set various ResolverOptions settings
and added lots of test cases to verify the options work.

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".

Michael J. Spencer e6203a57b5 Steal LLVM.h from Clang. This brings in very commonly used LLVM ADT/Support 
types into the lld namespace.

Michael J. Spencer cfd029fd91 Rearange header order to match llvm style. This exposed some missing types. 
Also fix some Platform.h includes that somehow got missed last time.

Nick Kledzik 6bc04c6904 Add support for SharedLibraryAtoms (proxy atoms for exported symbols from a 
shared library) and AbsoluteAtoms (proxy atoms for absolute address (e.g. ROM)).
Redesign weak importing as can-be-null-at-runtime and can-be-null-at-build-time.
Add lots of test cases for all the above.

Nick Kledzik f4fb2c5ac8 A couple of big refactorings: 1) Move most attributes of Atom down to DefinedAtom, so only atoms representing definitions need to implement them. 2) Remove definitionTentative, definitionWeak, mergeDuplicates, and autoHide. Replace with merge and interposable attributes. 3) Make all methods on Atom be virtual so that future object file readers can lazily generated attributes
