[Committed] Tidy up whitespace in df.h

[Roger Sayle]

The following trivial patch tidies up the indentation in the definitions
of the DF_ flags in df.h.  Although not clear in patch below, all of the
numeric flag values are now aligned.

The following patch was tested on i686-pc-linux-gnu with a full bootstrap,
all languages except treelang.  Committed to mainline CVS.
