Thanks for taking a look Slava, this is now ready for full review.

For the applications and benchmarks I measured, this patch did not make any measurable change to performance. This is unsurprising because many of these (e.g. spec2017) are well studied so I expect we would have already noticed if something like this were missing.

However, this change is expected to help for a benchmark in a future version of SPEC.
