Looks like these were added in r234668 in 2015, which would've been
Clang 3.6.2, according to:
http://releases.llvm.org/

I'd be fine with dropping the option check there.

There's a few here (-Qunused-arguments) that don't need cc-option
checks.  I recommend someone audit all of them, rather than send a
bunch of little patches.
