  [flang] Fold real-valued DIM()

Fold references to the intrinsic function DIM with constant real
arguments.  And clean up folding of comparisons with NaNs to address
a problem noticed in testing -- NaNs should successfully compare
unequal to all values, including themselves, instead of failing all
comparisons.
