  -----------
  [flang] Enforce fixed form rules about END continuation

>From subclause 6.3.3.5: a program unit END statement cannot be
continued in fixed form, and other statements cannot have initial
lines that look like program unit END statements.  I think this
is to avoid violating assumptions that are important to legacy
compilers' statement classification routines.
