Shankar Easwaran eeee23e60a This adds functionality for undefined atoms from dynamic libraries to be added
to the list of undefined atoms. 

The processing of undefined atoms from dynamic libraries is controlled by
use-shlib-undefines command line option. 

This patch also adds additional command line arguments to allow/disallow
unresolved symbols from shared libraries and mimics GNU ld behavior.

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 67f25272f1 [SymbolTable][Perf] Use hash_combine instead of a custom hash, also use memcmp.
ArrayRef<uint8_t>::equals(); lowers to a byte compare loop :(.

content. Also test if crypto hashing the content instead of full compare is
better.

Michael J. Spencer 602ffc13b8 [ELF][Reader] Refactor how relocations are read. Improves performance.
This changes from reading each relocation individually for each section to just
storing the range of relocations. It also counts the relocations to preallocate
