This was part of Bug 992845, but as the patch got r+ and the implementation was wrong I stripped the implementation from the previous patch such as it can land without dynamic slot support.

This patch adds support for MSlots, MGuardShape, MLoadSlot, MStoreSlot when we are escaping objects. The test case ensure that we can correctly recover the right values after the bailout, by reading both fixed slots and dynamic slots.
