Johannes Altmanninger 97969a9363 Restore error messages for bare variable assignment
Since #6287, bare variable assignments do not parse, which broke
the "Unsupported use of '='" error message.

This commit catches parse errors that occur on bare variable assignments.
When a statement node fails to parse, then we check if there is at least one
prefixing variable assignment. If so, we emit the old error message.
