Rafael Espindola a0af48fc93 Fix handling of files without a symbol table. 
This fixes a recent regression (r183338). Stripped elf files (like installed
crtn.o for example), are not required to have a symbol table. Handle that
correctly.

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 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
the _references array.

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.
