I think we need to come up with an alias like IS_GEN9_BC(), although I'm
not convinced about that paraticular name. The current (FOO || BAR) for
specific FOO and BAR is *much* faster to read than the slightly
confusing (GROUP && !SUBGROUP).
One other comment inline.

There's already superfluous braces to begin with, please don't add more!
Same all around.
