  -----------
  [flang] Warn on missing colons (C768)

In a derived type definition, a type bound procedure declaration
statement with neither interface nor attributes is required by constraint
C768 to have the optional "::" between the PROCEDURE keyword and the
bindings if any binding has a renaming with "=>".  The colons are
not actually necessary for a correct and unambiguous parse, so
emit a warning when they are missing.
