Details

With a nightly build of the Ion branch, Sunspider is about 10% slower than a m-c build.

Main problems are fannkuch (20 ms instead of 7) and base64 (15 ms instead of 5). With parallel compilation disabled I get normal scores on these tests, so I suppose it's related to parallel compilation, maybe GC, or something.

(And no it's not bug 849785, no DST yet in Europe.)
Bug 848849 seems to have fixed the problem on OS X. Keeping this open until I have verified this on Windows (waiting for the PGO build to finish).
Depends on: 848849
Did this end well?

Yep, tested this last week on Windows and SS is faster than on m-c now.
