    c++, openmp: Handle some OMP_*/OACC_* constructs during constant expression
evaluation [PR108607]

    While potential_constant_expression_1 handled most of OMP_* codes (by
saying that
    they aren't potential constant expressions), OMP_SCOPE was missing in that
list.
    I've also added OMP_SCAN, though that is less important (similarly to
OMP_SECTION
    it ought to appear solely inside of OMP_{FOR,SIMD} resp. OMP_SECTIONS).
    As the testcase shows, it isn't enough, potential_constant_expression_1
    can catch only some cases, as soon as one uses switch or ifs where at least
    one of the possible paths could be constant expression, we can run into the
    same codes during cxx_eval_constant_expression, so this patch handles those
    there as well.
