peter klausler 9a883bfa11 [flang] Clean up TODO comments and fix one (DATA constant ambiguity)
Remove resolved & moot TODO comments in Common/, Parser/,
and Evaluate/.  Address a pending one relating to parsing
ambiguity in DATA statement constants, handling it with
symbol table information in Semantics and adding a test.

peter klausler 04a147987a [flang] Include source information in an invalid file-unit-number message
An io-unit that is an internal-file-variable is syntactically identical
to a file-unit-number expression that is a variable reference.  An
ambiguous unit is initially parsed as an internal-file-variable.  If
semantic analysis determines that the unit is not of character type,
it is rewritten as an internal-file-variable.  This modification must
retain source coordinate information.

peter klausler 4acd8f7f0a [flang] Detect and rewrite ambiguous READ(CVAR)[,item-list]
READ(CVAR)[,item-list] with a character variable CVAR
could be parsed as an unformatted READ from an internal
unit or as a formatted READ from the default external unit
with a needlessly parenthesized variable format.  We parse
it as the former, but Fortran doesn't have unformatted
internal I/O.
