nine: Implement threadpool

DRI_PRIME setups have different issues due the lack of dma-buf fences
support in the drivers. For DRI3 DRI_PRIME, a race can appear, making
tearings visible, or worse showing older content than expected. Until
dma-buf fences are well supported (and by all drivers), an alternative
is to send the buffers to the server only when rendering has finished.
Since waiting the rendering has finished in the main thread has a
performance impact, this patch uses an additional thread to offload the
wait and the sending of the buffers to the server.

configure.ac: roll up a program for the sse4.1 check

So when checking/building sse code we have three possibilities:
 1 Old compiler, throws an error when using -msse*
 2 New compiler, user disables sse* (-mno-sse*)
 3 New compiler, user doesn't disable sse

The original code, added code for #1 but not #2. Later on we patched
around the lack of handling #2 by wrapping the code in __SSE4_1__.
Yet it lead to a missing/undefined symbol in case of #1 or #2, which
might cause an issue for #2 when using the i965 driver.

A bit later we "fixed" the undefined symbol by using #1, rather than
updating it to handle #2. With this commit we set things straight :)

To top it all up, conventions state that in case of conflicting
(-enable-foo -disable-foo) options, the latter one takes precedence.
Thus we need to make sure to prepend -msse4.1 to CFLAGS in our test.

v2: Clean the #includes. Suggested by Ilia, Matt & Siavash.

radeonsi: Disable asynchronous DMA except for PIPE_BUFFER

Using the asynchronous DMA engine for multi-dimensional operations seems
to cause random GPU lockups for various people. While the root cause for
this might need to be fixed in the kernel, let's disable it for now.

Before re-enabling this, please make sure you can hit all newly enabled
paths in your testing, preferably with both piglit and real world apps,
and get in touch with people on the bug reports below for stability
testing.

st/mesa: copy sampler_array_size field when copying instructions

The sampler_array_size field was added by "mesa/st: add support for
dynamic sampler offsets".  But the field wasn't getting copied in
the get_pixel_transfer_visitor() or get_bitmap_visitor() functions.

The count_resources() function then didn't properly compute the
glsl_to_tgsi_visitor::samplers_used bitmask.  Then, we didn't declare
all the sampler registers in st_translate_program().  Finally, we
asserted when we tried to emit a tgsi ureg src register with File =
TGSI_FILE_UNDEFINED.

Add the missing assignments and some new assertions to catch the
invalid register sooner.

Some of the geom shader tests produce an empty vertex shader,

cayman doesn't need the NOP workaround, so if the code arrives
here with no last_cf, just emit an END.

st/mesa: add a fallback for clear_with_quad when no vs_layer

Not all drivers can set gl_Layer from VS. Add a fallback that passes the
instance id from VS to GS, and then uses the GS to set the layer.

Tested by adding

  quad_buffers |= clear_buffers;
  clear_buffers = 0;

to the st_Clear logic, and forcing set_vertex_shader_layered in all
cases. No piglit regressions (on piglits with 'clear' in the name).
