In fact, the BSpec specifically says that this workaround is needed
for HSW, IVB, and VLV (no SNB).

I was apparently incorrect that it doesn't apply to Haswell when I
made commit f6db414f, although it did not regress anything. I just
tested disabling it on IVB as well -- everything still passes. So who
knows what's up.
