Summary: The addr64-based legalization is incorrect for MUBUF instructions with idxen set as well as for BUFFER_LOAD/STORE_FORMAT_* instructions. This affects e.g. shaders that access buffer textures. Since we never actually need the addr64-legalization in shaders, this patch takes the easy route and keys off the calling convention. If this ever affects (non-OpenGL) compute, the type of legalization needs to be chosen based on some TSFlag.
