Alexander Kornienko efde822cd1 [clang-tidy] Work around http://llvm.org/PR40392 
The readability-else-after-return check should be smarter about cases where the
variable defined in the condition is used in the `else` branch. This patch makes
it just ignore such cases, but alternative solutions may be better (added a
FIXME).

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.

Chandler Carruth 4a50956c07 Convert two more files that were using Windows line endings and remove 
a stray single '\r' from one file. These are the last line ending issues
I can find in the files containing parts of LLVM's file headers.

Kirill Bobyrev 34789edbbf [clang-tidy] enhance readability-else-after-return 
`readability-else-after-return` only warns about `return` calls, but LLVM Coding
Standars stat that `throw`, `continue`, `goto`, etc after `return` calls are
bad, too.

Daniel Jasper 3b6018b9f6 clang-tidy: Add initial check for "Don't use else after return". 
As per the LLVM coding standards:
http://llvm.org/docs/CodingStandards.html#don-t-use-else-after-a-return

Initial version, probably still quite a bit to do until this is really
useful.
