Peter Klausler faffcc3a46 [flang][runtime] Refine list-directed REAL(2) output ...

The rule used by list-directed REAL output editing to select
between Ew.d and Fw.d output editing breaks down for 16-bit
floating-point data, since the number of significant decimal
digits is so low that Ew,d output editing is nearly always selected.
Cap the test so that five-digit values will be output with Fw.d
editing.
