Improve performance of Immutable/SecureObjectPool/AllocFreeConcurrentStack

[benaadams]

@karelz could you assign this to me?

Be sure to test the perf fixes. We've made 'enhancements' to the pooling before that ended up making things worse.

[benaadams]

Agreed.

Question Immutable is OOP'd; there are improvements in corefx that I think it can take advantage of - do I also need to worry about regressions on netfx?

[AArnott]

That's a good question for @stephentoub. But I think most corefx perf fixes eventually get back-ported to netfx.
