use sese_l throughout scop-detection

Use sese_l throughout SCoP detection and create vec<scop_p> at the very end when
all SCoPs have been identified. 'struct sese_l' is very lightweight (two
pointers) compared to 'struct scop'.

No functional change intended. Passes regtest and bootstrap.

        (get_scops): New getter function.
        (remove_intersecting_scops): Use sese_l instead of scops_p.

        (subsumes): Same.

        detected.
