re PR testsuite/34168 (runtime tests in gfortran.dg/vect fail for unsupported [non-SSE2] targets)

PR testsuite/34168
        * lib/target-supports.exp (check_sse2_hw_available): New procedure.
        * gcc.dg/vect/vect.exp: Set dg-do-what-default to "compile"
        if SSE2 hardware is not available.
        * g++.dg/vect/vect.exp: Update target-dependent overrides to match
        gcc.dg/vect/vect.exp.
        * gfortran.dg/vect/vect.exp: Ditto.
        (check_effective_target_lp64_or_vect_no_align): Remove procedure.
