RFR (xs) 8075967: Zero interpreter asserts for SafeFetch<32, N> calls in ObjectMonitor

[David Holmes]

Hi Coleen,

Why generate stubs that can't be used and then add zero-specific logic 
to the shared CanUseSafeFetchN instead of not generating the stubs so 
that CanUseSafeFetchN will return false anyway ??

Thanks,
David
