    testsuite: Fix up vect-simd-clone1[678]*.c tests [PR108898]

    As mentioned in the PR, vect-simd-clone-1[678]{,f}.c tests FAIL on
    x86_64-linux with -m64/-march=cascadelake or -m32/-march=cascadelake,
    there are 3 matches for the calls rather than expected two.
    As suggested by Richi, this patch changes those tests to use
    --param vect-epilogues-nomask=0 such that it is more predictable on how
    many calls will show up.  In the non-[a-f] suffixed tests, the
    scan-tree-dump-times patterns were expecting 2 for non-aarch64 and 3 for
    aarch64, which is a puzzle for me, because vect_simd_clones effective
    target is apparently never true on aarch64 (just on x86 in some cases and
    on amdgcn; perhaps something to change for GCC14, but I guess too late
    for stage4).  That said, I have looked at aarch64 dumps and see only 2
    calls with --param vect-epilogues-nomask=0 and 3 with --param
    vect-epilogues-nomask=1 or without it, so I have tweaked those to always
    expect the same thing.  Another thing is some tests uselessly had
    -fdump-tree-optimized in dg-options even when they don't scan anything
    there.

    Tested on x86_64-linux with
    make -j32 -k check-gcc
RUNTESTFLAGS="vect.exp=gcc.dg/vect/vect-simd-clone-*.c \
   
--target_board='unix{-m64/-march=x86-64,-m64/-march=cascadelake,-m32/-march=i686,-m32/-march=cascadelake}'"
    and aarch64-linux (where all tests are UNSUPPORTED before/after).
