  -----------
  [flang][OpenMP] Better diagnostics for invalid or misplaced directives

Add two more AST nodes, one for a misplaced end-directive, and one for
an invalid string following the OpenMP sentinel (e.g. "!$OMP XYZ").

Emit error messages when either node is encountered in semantic analysis.
