[OPENMP][NFC]Release notes for OpenMP in clang (11.x).

[jdoerfert]

Nit: Maybe we should mention complex support on nvptx devices.

The rest looks good to me. Others might want to add stuff but we can merge this right away (IMHO)

Ok, will add.

That was the intention.

It is up to Hans if he has some time. But I think I covered almost all new features (+ complex for NVPTX), so after the update it can be merged with 11.x release.

[ABataev]

+ complex types for NVPTX

Present was added after 11.0 branching. Not aure about default(firstprivate)

[kkwli0]

default(firstprivate) was added in https://reviews.llvm.org/rG78443666bc18a6957d279a0f58319c8a3e57771a

Yest, it was before clang 11 was branched, so need to add to the list of the changes.

[ABataev]

Added default(firstprivate)

It's fine by me if you want to wait a day or two for more comments, or go ahead and merge directly.

Let's wait a day more then. Tomorrow it would be definitely ok to merge it with 11.x

Please go ahead and commit.

Hi Hans, can you commit it yourself? I have some technical issues and not able to commit it. And I don't know when it is going to be resolved. :(
