Rafael Espindola 3fd1e9933f Modernize raw_fd_ostream's constructor a bit. 
Take a StringRef instead of a "const char *".
Take a "std::error_code &" instead of a "std::string &" for error.

A create static method would be even better, but this patch is already a bit too
big.

Rafael Espindola a6e9c3e43a Remove system_error.h. 
This is a minimal change to remove the header. I will remove the occurrences
of "using std::error_code" in a followup patch.

Simon Atanasyan f97af8a084 [yaml2obj] Add new command line option `-docnum`. 
Input YAML file might contain multiple object file definitions.
New option `-docnum` allows to specify an ordinal number (starting from 1)
of definition used for an object file generation.

Patch reviewed by Sean Silva.

Ahmed Charles 56440fd820 Replace OwningPtr<T> with std::unique_ptr<T>. 
This compiles with no changes to clang/lld/lldb with MSVC and includes
overloads to various functions which are used by those projects and llvm
which have OwningPtr's as parameters. This should allow out of tree
projects some time to move. There are also no changes to libs/Target,
which should help out of tree targets have time to move, if necessary.

Sean Silva f99309cb08 [yaml2obj] Initial ELF support. 
Currently, only emitting the ELF header is supported (no sections or
segments).

The ELFYAML code organization is broadly similar to the COFFYAML code.

Sean Silva 741cebbea0 yaml2obj: add -format=<fmt> to choose input YAML interpretation 
See the comment in yaml2obj.cpp for why this is currently needed.
Eventually we can get rid of this, but for now it is needed in order to
make forward progress with adding ELF support, and should be
straightforward to remove later.

Also, preserve the default of COFF, to avoid breaking existing tests.
This policy can easily be changed later though.

Rafael Espindola fa4513a178 Split Alignment out of the Section Characteristics. 
The alignment is just a byte in the middle of Characteristics, not an
independent flag. Making it an independent field in the yaml
representation makes it more yamlio friendly.

Rafael Espindola ad3b97537b Simplify yaml2obj a bit. 
The COFFParser now contains only a COFFYAML::Object and the string table
(which is recomputed, not serialized).

The structs in COFFParser now all begin with a Header field with what is
actually on the COFF object. The other fields are things that are semantically
part of the struct (relocations in a section for exmaple), but are not actually
represented that way in the object file.

Rafael Espindola 4685073430 Remove COFFYAML::Header. 
Instead, use MappingNormalization to directly parse COFF::header. Also change
the naming convention of the helper classes to be a bit shorter.
