Tobias Grosser d1e33e7061 ScopDetection: Only detect scops that have at least one read and one write 
Scops that only read seem generally uninteresting and scops that only write are
most likely initializations where there is also little to optimize.  To not
waste compile time we bail early.

Tobias Grosser 1eedb67fa6 We do not support alias checks for base pointers defined inside the SCoP 
The run-time alias check places code that involves the base pointer at the
beginning of the SCoP. This breaks if the base pointer is defined inside the
SCoP. Hence, we can only create a run-time alias check if we are sure the base
pointer is not an instruction defined inside the scop. If it is we refuse to
handle the SCoP.

This commit should unbreak most of our current LNT failures.
