[Nomination] Adding Intel representatives to security group

We would like to nominate Andy Kaylor and Sergey Maslov to join the LLVM security group as a representative of Intel.  Both are members of the Intel compiler team, and would like to register as vendor contacts.  Intel packages and distributes LLVM-based toolchains as part of our compiler products.   As such, we would like to be aware of any security vulnerability found in the compiler, and would like to contribute to the resolution of such issues.

Please let us know if anything is missing from the nomination.
