  Issue Description

In Stmt._get_target(), the target is checked not to have a storage location in the case the context is constant. However, the check is missing for the case where the target is in transient storage. Given that the semantic analysis phase should make the compiler fail earlier if transient storage is accessed in a constant context, no impact of the missing check could be found.

should be fixed in #4015
