+ Enable speculative devirtualization optimization where a virtual call
+ can be transformed into a direct call under the assumption that its
+ object is of a particular type. A runtime check is inserted to validate
+ the assumption before making the direct call, and if the check fails,
+ the original virtual call is made instead. This optimization can enable
+ more inlining opportunities and better optimization of the direct call.
+ This is different from other whole program devirtualization optimizations
