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 :(.

TODO: Figure out if we are getting hash collisions, or just have a lot of equal
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
the _references array.

Michael J. Spencer 3e00c5015f [ELF][x86-64] Only emit a PLT entry for a PLT relocation if the target atom is a SharedLibraryAtom.

they are equal.

No test because it currently can't be tested. An upcomming patch will test it.

Chandler Carruth 21aaf2534d Switch a vector<pair<const T &, const U &>> to a vector<pair<const T *, 
const U *>>. Even in C++11 it doesn't seem this is valid as vector's
emplace support requires move assignment, and there is no way to move
assign a reference.

The real motivation however is that this fixes the build of lld with
libstdc++ 4.6.

Michael J. Spencer db18847b01 [ELF][Writer] Refactor Section to not have atoms. Move atoms into AtomSection. 
The purpose of this change is to simplify creating non-atom sections.
Previously _contentType, _sectionKind and _order were used for multiple
purposes and collided in places. This moves all of the Atom specific logic down
into AtomSection and makes Section just have raw Elf_Shdr flags.

Michael J. Spencer cfe59fd0d3 [Driver] Replace Target with TargetInfo. Simplify LinkerInput.

Michael J. Spencer 08b49bf27e [ELF][x86-64] Fix ifunc and add test. 
In an previous commit I managed to completely disable the IRELATIVE relocation

these issues and add a test. This test is quite brittle because there's no way
to do arithmetic on variables in FileCheck.

implicit move constructor. This is a bit of a hack, but it allows me to
build LLD in a bootstrap with libstdc++ which is my primary goal.
