Better Diagnostics

   These are things users might not ask about, or that need to be
looked into, before worrying about.  Also here are items that involve
reducing unnecessary diagnostic clutter.

   * When `FUNCTION' and `ENTRY' point types disagree (`CHARACTER'
     lengths, type classes, and so on), `ANY'-ize the offending `ENTRY'
     point and any _new_ dummies it specifies.

   * Speed up and improve error handling for data when repeat-count is
     specified.  For example, don't output 20 unnecessary messages
     after the first necessary one for:

INTEGER X(20) CONTINUE DATA (X(I), J= 1, 20) /20*5/ END

     (The `CONTINUE' statement ensures the `DATA' statement is
     processed in the context of executable, not specification,
     statements.)
