No longer require -fopenmp or -fopenacc with -E, unless specific version number options are also required for predefined macros. This means that most source can be preprocessed with -E and then later compiled with -fopenmp, -fopenacc, or neither. This means that OpenMP conditional compilation lines (!$) are also passed through to -E output. The tricky part of this patch was dealing with the fact that those conditional lines can also contain regular Fortran line continuation, and that now has to be deferred when !$ lines are interspersed.
