These tests all fail for me on i686-linux. The problem is
in the use of dg-options in gcc.dg/vect/, where it override all the various
needed vectorization options that need to be enabled on various arches
(e.g. -msse2 on i686).
Fixed thusly, tested on x86_64-linux and i686-linux, ok for trunk?

* gcc.dg/vect/vect-live-1.c: Remove dg-options. Add
dg-additional-options with just -fno-tree-scev-cprop in it.
* gcc.dg/vect/vect-live-2.c: Likewise.
* gcc.dg/vect/vect-live-5.c: Likewise.
* gcc.dg/vect/vect-live-slp-1.c: Likewise.
* gcc.dg/vect/vect-live-slp-2.c: Likewise.
* gcc.dg/vect/vect-live-slp-3.c: Likewise.
