[InferAddressSpaces] Mark ConstantAggregateZero as safe to cast to a ConstantExpr addrspacecast (#159695 )

This PR extends isSafeToCastConstAddrSpace to treat
ConstantAggregateZero like ConstantPointerNull.
Tests shows an extra addrspacecast instruction is removed and icmp
pointer vector operand's address space is now inferred.

This change is motivated by inspecting the test in commit f7629f5945f6.
