Ahmed Charles 13c70b6d4b Replace OwningPtr with std::unique_ptr.
This results in some simplifications to the code where an OwningPtr had to
be used with the previous api and then ownership moved to a unique_ptr for
the rest of lld.

Simon Atanasyan 9931f95bac Linking of shared libraries for MIPS little-endian 32-bit target.
The following are the most significant peculiarities of MIPS target:
- MIPS ABI requires some special tags in the dynamic table.
- GOT consists of two parts local and global. The local part contains
  entries refer locally visible symbols. The global part contains entries
  refer global symbols.
- Entries in the .dynsym section which have corresponded entries in the
  GOT should be:
  * Emitted at the end of .dynsym section
  * Sorted accordingly to theirs GOT counterparts
- There are "paired" relocations. One or more R_MIPS_HI16 and R_MIPS_GOT16
  relocations should be followed by R_MIPS_LO16 relocation. To calculate
  result of R_MIPS_HI16 and R_MIPS_GOT16 relocations we need to combine
  addends from these relocations and paired R_MIPS_LO16 relocation.

The patch reviewed by Michael Spencer, Shankar Easwaran, Rui Ueyama.

Shankar Easwaran 7915ff34b7 [lld][LinkingContext][ELF] Allow different output file types.
This adds an option --output-filetype that can be set to either
YAML/Native(case insensitive). The linker would create the outputs
associated with the type specified by the user.

Changes all the tests to use the new option.

Shankar Easwaran d26c8e3463 [lld][LinkingContext] Atoms created from command line options should be available in YAML
This adds an API to the LinkingContext for flavors to add Internal files
containing atoms that need to appear in the YAML output as well, when -emit-yaml
switch is used.

Flavors can add more internal files for other options that are needed.

Shankar Easwaran 2302bd5568 [lld] rename member variable name.
This renames variable name to reflect initial undefined symbols that are
defined by the linker -u option.

This doesnot change any functionality in lld, and updates code to reflect
Nick's comment.

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.
