Hi!
I'm getting:

vect "vectorized 1 loops" 2
on i686-linux (or x86_64-linux with -m32/-mno-sse).
The problem is that those tests use dg-options, which in */vect/ testsuite
throws away all the carefully added default options to enable vectorization
on each target (and which e.g. vect_int etc. effective targets rely on).
The old way would be to name those tests gcc.dg/vect/O3-pr101145*,
but we can also use dg-additional-options (which doesn't throw the default
options, just appends to them) which is IMO better so that we don't have to
rename the tests.
Tested on x86_64-linux and i686-linux, ok for trunk?

* gcc.dg/vect/pr101145.c: Use dg-additional-options with just -O3
instead of dg-options with -O3 -fdump-tree-vect-details.
* gcc.dg/vect/pr101145_1.c: Likewise.
* gcc.dg/vect/pr101145_2.c: Likewise.
