[Libclc-dev] Patches for copyright clean up

[Tom Stellard via Libclc-dev]

Hi,

I've submitting two changes to bring the project into compliance with LLVM policy.
One to remove license headers from files: https://reviews.llvm.org/D24929
and one to remove non-UIUC / non-MIT licensed code: https://reviews.llvm.org/D24930
I'm hopeful we will be able to re-add the removed code, but I need to get approval
from the LLVM foundation.

Let me know if you have any questions.

Thanks,
Tom
