Michael J. Spencer ce1e53e19c Correctly pass ownership of MemoryBuffers.

Shankar Easwaran a4323a5cca This fixes a SIGSEGV failure in ReaderArchive while trying to trace what
InputFile is being pulled from the Archive library to resolve a symbol. 

The buffer which was being used was already being handed over to the
MemoryBuffer object and was being accessed after the hand over. 

Moving it before the buffer is handed over.

Nick Kledzik c314b46e71 This is my Driver refactoring patch.
The major changes are:
1) LinkerOptions has been merged into TargetInfo
2) LinkerInvocation has been merged into Driver
3) Drivers no longer convert arguments into an intermediate (core) argument 
   list, but instead create a TargetInfo object and call setter methods on 
   it. This is only how in-process linking would work. That is, you can 
   programmatically set up a TargetInfo object which controls the linking.
4) Lots of tweaks to test suite to work with driver changes
5) Add the DarwinDriver
6) I heavily doxygen commented TargetInfo.h

Things to do after this patch is committed:
a) Consider renaming TargetInfo, given its new roll. 
b) Consider pulling the list of input files out of TargetInfo. This will 
   enable in-process clients to create one TargetInfo the re-use it with 
   different input file lists.
c) Work out a way for Drivers to format the warnings and error done in 
   core linking.

Michael J. Spencer 6580d1f226 Set ordinals correctly.
This actually doesn't change behavior with the current LinkerInvocation, but
it's needed when you make reading parallel.

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.
