Add RSInvariant pass to recognize Load from RsExpandKernelDriverInfo as invariant. This allows more-aggressive optimization of foreachexp-generated code and of the rsGet*(rs_kernel_context) API functions. In particular, it facilitates LICM of Loads out of the wrapper loop in a .expand function. Bug: 18964628 Change-Id: I77a87b325724ca08c4a04f5a46f316be78a5e0fd
