I'm so excited to see this getting close! Are our build bots warning-less at this point? I don't think we should land this until the build bots do not have any warnings.

Me too :) I think I'll upload this patch once more after the other patches are landed (to check that it builds). Thanks for reviewing!

The patch also builds with VS2015 Update 3.

This adds /wd4206 (nonstandard extension used : translation unit is empty) and /wd4722 ('function': destructor never returns, potential memory leak).  Why do we need to add 4722?

It broke the ApplecWindows and WinCairo build, see build.webkit.org for details.

This was added because of the following code:

JITWorklist::~JITWorklist()
{
    UNREACHABLE_FOR_PLATFORM();
}
