Merge commit 3552d3e0f from llvm git (by Simon Atanasyan):

  [mips] Add `octeon+` to the list of CPUs accepted by the driver

This is one of the upstream changes needed for adding support for the
OCTEON+ CPU type, so that we can test Clang builds using the most
commonly available FreeBSD/mips64 reference platform, the Edge Router
Lite.
