llvmpipe: avoid flushing depth buffer cache on swapbuffers

There's no need to push out depth buffer contents on swapbuffers.

Note that this change doesn't throw away depth buffer changes, it simply
holds them in the cache over calls to swapbuffers.  The hope is
that swapbuffers will be followed by a clear() which means in that case
we won't have to write the changes out.

llvmpipe: shortcircuit repeated lookups of the same tile

The lp_tile_cache is often called repeatedly to look up the same
tile.  Add a cache (to the cache) of the single tile most recently
retreived and make a quick inline check to see if this matches the
subsequent request.

Add a tile_address bitfield struct to make this check easier.
