Might be a bit of a bigger refactor than you're looking to do here, but the AArch64 backend is a much better model for this: ISA features, and Tune features are separated out into parallel lists.

Agree, RISCV is doing that as well. Though I believe doing such separation for PPC is out of the scope of this patch.
