PATCH: document new real.h macros

[Ben Elliston]

This little documentation update slipped through when I merged the
real.h/real.c changes from the dfp-branch.  Tested with a `make info

        * doc/tm.texi (Data Output): Add REAL_VALUE_TO_TARGET_DECIMAL32,
        REAL_VALUE_TO_TARGET_DECIMAL64 and REAL_VALUE_TO_TARGET_DECIMAL64
        macros.
