    testsuite: Fix gcc.dg/vect/pr101145* tests [PR101145]

    I'm getting:

scan-tree-dump-times 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/ testsu=
ite
    throws away all the carefully added default options to enable vectoriza=
tion
    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 defa=
ult
    options, just appends to them) which is IMO better so that we don't hav=
e to
    rename the tests.
