radeonsi/gfx10: implement hardware MSAA resolve
MSAA is only supported for 64KB_{R,Z}_X modes, so the micro tile optimization that we use on gfx9 and earlier does not work. Be very explicit about how the swizzle mode of the temporary surface is selected. Acked-by: Bas Nieuwenhuizen <[email protected]>
