This implements a solution for constant initializers suggested by Vadim Girlin, where we store the data after the shader code and then use the S_GETPC instruction to compute its address. This saves use the trouble of creating a new buffer for constant data and then having to pass the pointer to the kernel via user SGPRs or the input buffer. llvm-svn: 213530
