Better patch

I am attaching more complete patch.  There is quite bad wrong code bug in
pure-const that updates declaration because it proves that one of inline clones
is pure which does not imply that the offline copy is.
The patch also need fix to tree-inline.c that I sent earlier and Richard
requested a cleanup for http://gcc.gnu.org/ml/gcc-patches/2014-02/msg00134.html
Will do that tomorrow.
