[Bug libfortran/20278] Performance of formatted output

[fxcoudert at gcc dot gnu dot org]

Changed the title of the PR to the more general "Performance of formatted
output". My experience is that using sprintf to output float values is where
performance could be gained (computation of the logarithm of the written value
is done twice, for example). *But* that would require a home-made
floating-point I/O system, which is far from trivial to implement.

Oh, I'm also switching priority of this to enhancement, since we don't perform
too bad (20% slower than Intel, 100% slower than g77) and formatted I/O isn't
usually done on very big arrays.
