testsuite: Fix up gomp/simd-{2,3}.c tests [PR98243]
The test (intentionally) is not gcc.dg/vect/, as it needs -fopenmp and uses
OpenMP directives other than simd and therefore can't rely on default
VECTFLAGS and so I think can't safely use vect_int effective target
either. So, I'm just making sure it is vectorized on x86 and on aarch64 (the
latter as an example of a target that doesn't need any extra options to get
the vectorization).

* gcc.dg/gomp/simd-2.c: Add -msse2 on x86. Restrict
scan-tree-dump-times to x86 and aarch64 targets.
* gcc.dg/gomp/simd-3.c: Likewise.
