The pattern used to match an inline finalizable test might be incorrect in 64-bit mode as tree simplification might result in 32-bit operations being used. This change accounts for that possibility by checking whether an l2i was applied to the result of the load of isClassAndDepthFlags, and checks for 32-bit operations accordingly.
Fixes: Issue #4885
