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.

This just removes the usage of llvm::reverse and llvm::seq. That makes
it harder to handle the empty case correctly and so I've also added
a test there.
This is just a shot in the dark at what might be behind the buildbot
failures. I can't reproduce any issues locally including with ASan...
I feel like I'm missing something...

This is both convenient and more efficient as we can skip any
intermediate reallocation of the vector.
This usage pattern came up in a subsequent patch on the pass manager,
but it seems generically useful so I factored it out and added unittests
here.

re-insertion of entries into the worklist moves them to the end.
This is fairly similar to a SetVector, but helps in the case where in
addition to not inserting duplicates you want to adjust the sequence of
a pop-off-the-back worklist.
I'm not at all attached to the name of this data structure if others
have better suggestions, but this is one that David Majnemer brought up
in IRC discussions that seems plausible.
I've trimmed the interface down somewhat from SetVector's interface
because several things make less sense here IMO: iteration primarily.
I'd prefer to add these back as we have users that need them. My use
case doesn't even need all of what is provided here. =]
I've also included a basic unittest to make sure this functions
reasonably.
