C++ PATCH to stop folding constants to their values in convert_like_real

Authentication-results: sourceware.org; auth=none

Something that was missed previously in the delayed folding work:
there's no good reason to be pulling values out of constants in
convert_like_real.

With that fixed, I needed to change cp_fully_fold to use
cp_fold_rvalue so that it would properly pull out constant values in
C++98 mode.

Tested x86_64-pc-linux-gnu, applying to trunk.
