doc: Fix docs for -dD regarding predefined macros
The manual has always claimed that -dD differs from -dM by not
outputting predefined macros, but that's untrue. It has been untrue
since GCC 3.0 (probably with the change to use libcpp as the default
preprocessor implementation).
gcc/ChangeLog:
* doc/cppopts.texi: Remove incorrect claim about -dD not
outputting predefined macros.
