bf6e3f9257 [DWARF parser] Teach DIContext to fetch short (non-linkage) function names for a given address. 
Change --functions option in llvm-symbolizer tool to accept
values "none", "short" or "linkage". Update the tests and docs
accordingly.

b043c3d94a [DWARF parser] Use enums instead of bitfields in DILineInfoSpecifier. 
It is more appropriate than the current situation, when one flag
(AbsoluteFilePath) is relevant only if another flag is set.

This refactoring would also simplify fetching the short function name
(stored in DW_AT_name) instead of a linkage name returned currently.

No functionality change.

08ef0202ce [DWARF parser] Turn DILineInfo into a struct. 
Immutable DILineInfo doesn't bring any benefits and complicates
code. Also, use std::string instead of SmallString<16> for file
and function names - their length can vary significantly.

No functionality change.

f4ccd11075 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.

efdbec8b0a Simplify the handling of iterators in ObjectFile. 
None of the object file formats reported error on iterator increment. In
retrospect, that is not too surprising: no object format stores symbols or
sections in a linked list or other structure that requires chasing pointers.
As a consequence, all error checking can be done on begin() and end().

This reduces the text segment of bin/llvm-readobj in my machine from 521233 to
518526 bytes.

1fca78a9b1 Return an ErrorOr<Binary *> from createBinary. 
I did write a version returning ErrorOr<OwningPtr<Binary> >, but it is too
cumbersome to use without std::move. I will keep the patch locally and submit
when we switch to c++11.
