Tobias Grosser 2dc1f547ae [tests] Make sure tests do not end in 'unreachable' 
There is no point in optimizing unreachable code, hence our test cases should
always return.

This commit is part of a series that makes Polly more robust on the presence of
unreachables.

Michael Kruse 426e6f71f8 [ScopInfo] Fix: use raw source pointer. 
When adding an llvm.memcpy instruction to AliasSetTracker, it uses the raw
source and target pointers which preserve bitcasts.
MemAccInst::getPointerOperand() also returns the raw target pointers, but
Scop::buildAliasGroups() did not for the source pointer. This lead to mismatches
between AliasSetTracker and ScopInfo on which pointer to use.

Fixed by also using raw pointers in Scop::buildAliasGroups().
