Subject: [4.3] making a few real functions work with dfp

:ADDPATCH middle-end / dfp:

This patch makes exact_real_truncate() and real_isinteger() handle dfp
values correctly. In order to do so, it adds a decimal_normalize()
function that normalizes a decimal floating point number.

Bootstrapped and tested with --enable-languages=all
--enable-decimal-float for trunk revision 118920 on i686-pc-linux-gnu

   * dfp.c (decimal_normalize): Define.
   * dfp.h (decimal_normalize): Declare.
   * real.c (normalize): Normalize also dfp values.
   (exact_real_truncate): Work also when truncating from dfp to
binary and viceversa.
   (real_isinteger): Add dfp support.
