SDMA support was dropped in 1f31a21664 mainly because the
advantages of delegating some copy/clear operations to the
SDMA hw came with large drawbacks: CPU overhead due to the
sdma/gfx synchronization and hangs.
This commit restores SDMA support for all gfx7+ chips but
only for the image copy operations.
SDMA operations won't be intertwined with gfx operations
like before. Instead, a SDMA IB will contain a single copy
at a time and the synchronization will be handled by the
winsys (based on the used buffers).

This helps some viewperf subtests.
Only view XY culling is done. Edgeflags are always disabled with lines.

Do it when we bind shaders.
The advantages are:
- no need to memset the fields when any shader variant state is changed
(e.g. culling on/off)
- no need to recompute the fields every time that happens

We would like draw-only display lists to have immutable draw info and
this is the only GL non-draw state in pipe_draw_info (not counting
view_mask).
It also allows removing some code from draw_vbo for tessellation.

When this flag is set, u_threaded_context will try not to map it directly
for better buffer placement. It's set by drivers when visible VRAM is too
small.

The GDS ordered append variant is unstable due to kernel and firmware bugs.
The unordered GDS variant isn't faster than the memory-based variant.
Only the memory-based variant is kept.

Determine if a given shader write the same constant value to its output
if a specific input texture is replaced by constant load.
It's done by checking if the store_output intrinsics only depends on
constant and a texture. If it's true, the given texture is replaced by
a constant load in cloned shader and this clone is optimized.
Then the output is checked (= is it constant or not).

This allows to implement custom draw_vbo code-path without
touching si_draw_vbo.
As an example, skipped all draw calls with an odd new_draws
could be done like this:
void mywrapper(...) {
if (new_draws % 2)
return;
return sctx->real_draw_vbo(...);
}
if (some_condition_is_met)
si_install_draw_wrapper(sctx, mywrapper);
Instead of having to add the "if ()" condition inside si_draw_vbo.
Note that a single wrapper may be installed so care must be taken
to not override an existing wrapper.

the only case in which this is nonzero is if a multidraw gets split by the frontend,
i.e., mesa core, and in all other cases it can be ignored. the value can also be ignored
for all indirect draws, though it seems many (most?) gallium drivers are not aware of this

this moves index_bias into the multidraw struct, enabling draws where the value
changes to be merged; the draw_info struct member is renamed and moved to the end
of the struct for tc use
u_vbuf still has some checks to split draws if index_bias changes, maybe
this can be removed at some point?
