Alexander Aprelev a7c612e187 [vm/resolution] Wrap few Class::Lookup.*FunctionUnsafe() methods in Resolver::Resolve.*() methods.
Add "Unsafe" suffix to those Class::Lookup* methods to indicate they will need program
structure protection locking.

This allows to localize program structure protection locking inside of those Resolver methods.
