Before our rewrite of the scop detection, we used to not have a valid SESE

by trying to prove that at all levels of a loop nest the data references would
be still valid.
Now that we have a valid SESE region, we can call the scev analysis in the same
way on the same computed loop nest in the scop-detection as in the sese-to-poly.
Next step will be to cache the data references analyzed in the scop detection
and not compute the same info in sese-to-poly.
The patch fixes block-1.f90 that used to ICE on x86_64-linux when compiled with
-m32. Patch passed bootstrap with BOOT_CFLAGS="-g -O2 -fgraphite-identity
-floop-nest-optimize" and check on x86_64-linux using ISL-0.15.
Nice.
