Ugh, dfp is complete mess, in many places in the folder, middle-end and
optimizers dconst{1,2,m1,half} are used even for decimal types/modes, but those
real formats are binary, not decimal.  The following patch just accepts the
status quo and handles those 4 standard constants specially instead of ICEing
on them.
