PTAL

Expected differences: We now have CAN_USE_VFP32DREGS off.
This only impacts snapshot creation and there it's better to use the smallest
snapshot possible. Furthermore, it's the same way chrome creates our snapshots
ATM.

_GLIBCXX_DEBUG=1 is off now in debug just like on linux32 platform (already
discussed there).
