8.2.0: don't enable -fstack-clach-protection by default

In bug #675050 I noticed that -fstack-clash-protection is enabled
not just for hardened users but for USE=ssp users as well.

That was not an intention of the patch. The change enables
-fstack-clach-protection only for -DEXTRA_OPTIONS (hardened users).

See https://bugs.gentoo.org/675050 for longer-term plans to
enable -fstack-clach-protection for more users.

+Subject: [PATCH] Fix invalid assumption in vect_transform_stmt (PR 86871)
+
+The handling of outer-loop uses of inner-loop definitions assumed
+that anything that wasn't a PHI would be a gassign.  It's also
+possible for it to be a gcall.

8.2.0: pull 10_all_default-fortify-source.patch from Debian, bug #621036

glibc and other packages expect _FORTIFY_SOURCE define to be a number.
Before the patch _FORTIFY_SOURCE was
    ((defined __OPTIMIZE__ && __OPTIMIZE__ > 0) ? 2 : 0)
After the patch it's
    2
(or not set if build is unoptimised).

8.2.0: drop libstdc++ libking against libvtv

libstdc++ itself provides weak symbols to work
both against present and missing libvtv. Final
binary desides whetned to use vtv or not by
linking against libvtv.

8.2.0: restore -Werror patches

Five new patches that drop -Werror:
+ 105_all_libgfortran-Werror.patch
+ 106_all_libgomp-Werror.patch
+ 107_all_libitm-Werror.patch
+ 108_all_libatomic-Werror.patch
+ 109_all_libbacktrace-Werror.patch

The patches are no really new: last time Gentoo applied
them on gcc-4.9.x branch but after 5.x they were lost.

Need for them resurfaces after series of fixes that allowed
user to tweak CXXFLAGS (bug #581406)
