Rui Ueyama e96044a370 [lld] Move AtomLayout from ELF to ReaderWriter so that it can be used by non-ELF writers.

Shankar Easwaran 87a594835f [lld][ELF][x86_64,hexagon] Changed dynamic atoms to live in anonymous namespace 
so that their names are hidden.

This addresses comments raised by Sean/Rafael.

Shankar Easwaran 9af77a2cab [lld][ELF][All Archs] Addend is used by dynamic relocations 
only if they are relative. This removes the FIXME when the
relocations are being emitted and checks if the relocation
is relative and only then populates the addend information.

I couldnt add a testcase for this as llvm-readobj lacks     
functionality of printing dynamic relocations.              

When the functionality is added, remove the commented lines
from elf/ifunc.test to test functionality.

Michael J. Spencer 75ed350132 [ELF] Initialize readers and writers on creation. 
This makes the target handler a constructor argument because the constructor of
OutputELFWriter relies on it being initialized.

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.
