This commit adds 2 new instructions in the selector: - OpAccessChain - OpInBoundsAccessChain. The choice between the two relies on the `inbounds` marker. Those instruction are not used for OpenCL, to maintain the same behavior as previously. They are only added when building for logical SPIR-V, as it doesn't support the pointer equivalent. Because logical SPIR-V doesn't support pointer cast either, the assign_ptr_type intrinsic need to be generated so OpAccessChain gets lowered with the correct pointer type, instead of i8*.
