Jonas Devlieghere 6ba7992031 [LLD] Migrate llvm::make_unique to std::make_unique
Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Rui Ueyama 3f851704c1 Move new lld's code to Common subdirectory.
New lld's files are spread under lib subdirectory, and it isn't easy
to find which files are actually maintained. This patch moves maintained
files to Common subdirectory.

Zachary Turner 264b5d9e88 Move Object format code to lib/BinaryFormat.
This creates a new library called BinaryFormat that has all of
the headers from llvm/Support containing structure and layout
definitions for various types of binary formats like dwarf, coff,
elf, etc as well as the code for identifying a file from its
magic.

Lang Hames 560333749f [lld][MachO] Add debug info support for MachO.
This patch causes LLD to build stabs debugging symbols for files containing
DWARF debug info, and to propagate existing stabs symbols for object files
built using '-r' mode. This enables debugging of binaries generated by LLD
from MachO objects.

Pete Cooper 514594bdd3 Convert a few macho reader/writer helpers to new error handling. NFC.
These methods were responsible for some of the few remaining calls
to llvm::errorCodeToError.  Converting them makes us have more Error's
in the api and fewer error_code's.

Pete Cooper e82f3a099f Copy MachO struct to temporary to avoid unaligned load UB.
We were already copying this data to a temporary for endian swaps.  Now
we just always copy it, but still only do the endian swaps when needed.

Pete Cooper ceee5de088 Generate version min load commands when the platform is unknown.
In the case where we are emitting to an object file, the platform is
possibly unknown, and the source object files contained load commands
for version min, we can take the maximum of those min versions and
emit in in the output object file.

This test also tests r259739.

Rafael Espindola c08ab8e6e4 Delete unnecessary generality in loadFile.
loadFile could load mulitple files just because yaml has a feature for
putting multiple documents in one file.

Designing a linker around what yaml can do seems like a bad idea to
me. This patch changes it to read a single file.

There are further improvements to be done to the api and they
will follow shortly.

Rui Ueyama f006f4d62c Define an implicit constructor which takes actual alignment value to PowerOf2.
The new constructor's type is the same, but this one takes not a log2
value but an alignment value itself, so the meaning is totally differnet.

Rui Ueyama c3d18f5120 Remove implicit constructor and operator int from PowerOf2.
This patch is to make instantiation and conversion to an integer explicit,
so that we can mechanically replace all occurrences of the class with
integer in the next step.

Now get() returns an alignment value rather than its log2 value.
