i965: Add a few assertions on lossless compression
v2 (Ben): Use combination of msaa_layout and number of samples instead of introducing explicit type for lossless compression (intel_miptree_is_lossless_compressed()). Signed-off-by: Topi Pohjolainen <[email protected]> Reviewed-by: Ben Widawsky <[email protected]>
