VM Crash

Here is a small test that lead to VM crash in Dolphin 6.02:

r := RandomCRT new.
100000 timesRepeat: [ (r next negated asFraction/10) asInteger ]

Dolphin 5 stays alive.

And does not crash with an intermediate #asFloat message:

r := RandomCRT new.
100000 timesRepeat: [ (r next negated asFraction/10) asFloat asInteger
]

This appears to be a bug in the VM large integer division primitive. You can
reproduce it more simply as follows:

u := -2**63-1.
v := 2**96-1.
u quo: v. "Bang!"

We'll fix this in the forthcoming release.
