Eric Beckmann c8dba240b1 Revert "Revert "Revert "Revert "Switch external cvtres.exe for llvm's own resource library.""""
This reverts commit 147f45ff24456aea59575fa4ac16c8fa554df46a.

Revert "Revert "Revert "Revert "Replace trivial use of external rc.exe by writing our own .res file.""""

This reverts commit 61a90a67ed54a1f0dfeab457b65abffa129569e4.

The patches were intially reverted because they were causing a failure
on CrWinClangLLD.  Unfortunately, this was done haphazardly and didn't
compile, so the revert was reverted again quickly to fix this.  One that
was done, the revert of the revert was itself reverted.  This allowed me
to finally fix the actual bug in r307452.  This patch re-enables the
code path that had originally been causing the bug, now that it (should)
be fixed.

Eric Beckmann 81979b038f Revert "Revert "Revert "Replace trivial use of external rc.exe by writing our own .res file."""
This reverts commit 5fecbbbe5049665d86834cf69d8f75db4f392308.

The initial revert was done in order to prevent ongoing errors on
chromium bots such as CrWinClangLLD.  However, this was done haphazardly
and I didn't realize there were test and compilation failures, so this
revert was reverted.  Now that those have been fixed, we can revert the
revert of the revert.

Eric Beckmann 8cc9fd31e6 Revert "Replace trivial use of external rc.exe by writing our own .res file."
This patch still seems to break CrWinClangLLD, reverting this once more
until I can discover root problem.

Eric Beckmann 602afcf7e9 Revert "Revert "Replace trivial use of external rc.exe by writing our own .res file.""
Summary:
This reverts commit 51931072a7c9a52540baf76fc30ef391d2529a2f.

This revert was originally done because the integrations of the new
WindowsResource library into LLD was causing error in chromium, due to
bugs in how resource sections were handled.  These bugs were fixed,
meaning that the features may be reintegrated.

Eric Beckmann d40dd64ff0 Revert "Replace trivial use of external rc.exe by writing our own .res file."
This reverts commit d4c7e9fc63c10dbab0c30186ef8575474a704496.

This is done in order to address the failure of CrWinClangLLD etc. bots.
These throw an error of "side-by-side configuration is incorrect" during
compilation, which sounds suspiciously related to these manifest
changes.

Revert "Switch external cvtres.exe for llvm's own resource library."

This reverts commit 71fe8ef283a9dab9a3f21432c98466cbc23990d1.

Eric Beckmann 2a81089116 Replace trivial use of external rc.exe by writing our own .res file.
This patch removes the dependency on the external rc.exe tool by writing
a simple .res file using our own library. In this patch I also added an
explicit definition for the .res file magic.  Furthermore, I added a
unittest for embeded manifests and fixed a bug exposed by the test.

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.
