Arnold Schwaighofer 76dca58c66 BasicAA: GEPs of NoAlias'ing base ptr with equivalent indices are NoAlias 
If we can show that the base pointers of two GEPs don't alias each other using
precise analysis and the indices and base offset are equal then the two GEPs
also don't alias each other.
This is primarily needed for the follow up patch that analyses NoAlias'ing PHI
nodes.

Part 1/2 of fix for PR13564.
