[kotlarmilos]

Looks like a regression - @stephentoub could you take a look if the following commit affected the performance?

2058d5e

[stephentoub]

The HashSet/Dictionary improvements and regressions are likely related to 2058d5e, though there are other regressions here that aren't related.

Are those regressions on the mono interpreter? The JIT? AOT? The change relies on a pattern like:

if (typeof(T).IsValueType) { ... }

where that typeof(T).IsValueType will be converted into a constant, the branch eliminated, and the whole body of that if block removed for non-value types. Will that happen in the environment in which this regressed?
