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).

	--param vect-epilogues-nomask=0 to dg-additional-options.
	* gcc.dg/vect/vect-simd-clone-17.c: Likewise.  Always expect just 2
	foo.simdclone calls.
	* gcc.dg/vect/vect-simd-clone-17d.c: Remove -fdump-tree-optimized from
	dg-additional-options.
	* gcc.dg/vect/vect-simd-clone-17e.c: Likewise.
	* gcc.dg/vect/vect-simd-clone-17f.c: Likewise.  Add
	--param vect-epilogues-nomask=0 to dg-additional-options.
	* gcc.dg/vect/vect-simd-clone-18.c: Add --param vect-epilogues-nomask=0
	to dg-additional-options.  Always expect just 2 foo.simdclone calls.
	* gcc.dg/vect/vect-simd-clone-18f.c: Add
	--param vect-epilogues-nomask=0 to dg-additional-options.
