[Bug c/24451] New: [gomp] Return out of parallel loop not rejected

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following code is accepted with -fopenmp although a return from a
parallel for loop is not allowed:

================================
void foo()
{
    int i;
#pragma omp parallel for
    for ( i=0; i<10; ++i )
        return;
}
================================

When a value is returned, we get an ICE instead:

================================
int foo()
{
    int i;
#pragma omp parallel for
    for ( i=0; i<10; ++i )
        return 0;
}
================================

bug.c: In function '__omp_fn.1':
bug.c:4: internal compiler error: in expand_expr_real_1, at expr.c:8307
Please submit a full bug report, [etc.]

The same holds for the C++ frontend; the ICE is just in a different position.
