Using checked int64 op codes yeild Mono runtime crash.

How often does this happen? 
Every time.

Additional Information:
The easiest way to repro this is to use the F# Interactive window (FSI.exe),
however this also repros on compiled F# code too. Meaning that this isn't
isolated to just Reflection.Emit. Here is a console sesson reproing the bug.
