Sharing code between c1 and the interpreter definitely makes sense if
possible. I think we would rather implement the check as platform
independent IR in C2 which should lead to better generated code. That
makes sharing with C2 impossible.
Anyway, I'm sure we would welcome a patch that implements shared storage
property checks for c1 and the interpreter on x86 if you feel like
