The docs say "When performing a render target resolve, PIPE_CONTROL with end
of pipe sync must be delivered.", which doesn't actually tell us whether we
need to do it before or after. Blorp did it before and after, and doing it
before certainly makes sense. The resolve operation needs to read from the
MCS and if we don't flush the render cache it won't get up-to-date data.
On the other hand, doing it after should not be necessary, since we call
brw_render_cache_set_check_flush() after the resolve.
Fixes rendering corruption in kwin's cover switch effect and various steam
games.

Based on the old code, the new layout code describes the layout with the new,
well-documented, ilo_layout. It also gains new features such as MCS support
and extended ARYSPC_LOD0 that i965 comes up with (see
6345a94a9b).
Instead create a staging texture with pipe_buffer_create and
PIPE_USAGE_STAGING.
u_upload_mgr sets the usage of its staging buffer to PIPE_USAGE_STREAM.
But since 150ac07b85 CPU -> GPU streaming buffers
are created in VRAM. Therefore the staging texture (in VRAM) does not offer any
performance improvements for buffer downloads.

The next patch adds a foreach_block (block, cfg) macro, which works
better if it provides a direct bblock_t pointer, rather than a
bblock_link pointer that you have to use to find the actual block.
