Hi Danno,
Here is a rebase of what you reviewed before. It's exactly the same :).

Two things,
1) Only ia32 and x64 ports are in place yet, and
2) Another patch is coming which avoids deopt out of the elements grow stub for
the case we fall into old or large object space.

Thanks,
--Michael

Hi Danno,
Slight change o' strategy.
I'd like to land this CL. The extra work which avoids bailout on large array
allocations has issues to debug, and it's not clear that the performance
improvement is worthwhile.

This CL combined with your follow on to avoid math deopts in Kraken is a good
combo.

Thanks,
--Michael
