[PATCH] Bug 18582 - Offset overflow on calling __chkstk and __alloca on x64

[Reid Kleckner]

I went ahead and put together a patch that I think does the right thing here:

Note it doesn't touch EmitLoweredWinAlloca, but that code is a mess and IMO should be refactored to use the fixed code separately.
