[PATCH] Allow to model non-affine control flow in a SCoP.

Now I am confused. Look for "AllowNonAffineBranches" in
ScopDetection.cpp. At least my idea was that this switch would prevent
any non-affine branches to be allowed in a SCoP, hence if turned off
(default) nothing should change.

I will push the codegen for review after I run it with lnt.
