Mikael Holmen 828d0d9643 [LSR] Pointers with different address spaces are considered incompatible. ...

Summary:
Function isCompatibleIVType is already used as a guard before the call to

 SE.getMinusSCEV(OperExpr, PrevExpr);

in LSRInstance::ChainInstruction. getMinusSCEV requires the expressions
to be of the same type, so we now consider two pointers with different
address spaces to be incompatible, since it is possible that the pointers
in fact have different sizes.
