gcc6-pr69677.patch

I'm currently bootstrapping/regtesting --with-arch=corei7 --with-cpu=corei7
--with-fpmath=sse i686-linux compiler with this patch, and got already well
past the spot where it previously ICEd.
The patch should restore STV behavior to the previous one, except for the
non-default lower preferred/incoming stack boundaries.
