ddebug: simplify watchdog loop and fix crash in the no-timeout case

  API thread               Gallium thread            Watchdog
  ----------               --------------            --------
  dd_before_draw

  dd_after_draw

Alternatively, the same scenario would assert in a debug build when
destroying the record because record->driver_finished has not signaled.

Fix this and simplify the logic at the same time by

4 components (e.g, r32f, rg32i, etc) this results in extra mov
instructions.

This patch uses the actual number of components from the image format.

For example, in a shader like:

layout (r32f, binding=0) writeonly uniform imageBuffer u_image;
...
void main(void) {
   ...
   imageStore (u_image, some_offset, vec4(1.0));
   ...
}

instruction count is reduced in at least 3 instructions (note image
format is r32f, 1 component only).

This obviously reduces register pressure as well.

st/dri: allow both render and sampler compatible dma-buf formats

Currently all the EGL APIs are missing a way to specify how an imported
dma-buf is intended to be used. Demanding the format to be both usable
for sampling and rendering artificially restricts the list of formats a

Looking at how the Intel driver implements those DRI2 image APIs it

this patch aligns behavior between Intel and Gallium based drivers.

i965/vec4/dce: Don't narrow the write mask if the flags are used

In an instruction sequence like

            cmp(8).ge.f0.0 vgrf17:D, vgrf2.xxxx:D, vgrf9.xxxx:D
    (+f0.0) sel(8) vgrf1:UD, vgrf8.xyzw:UD, vgrf1.xyzw:UD

The other fields of vgrf17 may be unused, but the CMP still needs to
generate the other flag bits.

To my surprise, nothing in shader-db or any test suite appears to hit
this.  However, I have a change to brw_vec4_cmod_propagation that
creates cases where this can happen.  This fix prevents a couple dozen
regressions in that patch.

quite a bit of per-allocation overhead (due to ralloc), so the patch was
followed by a patch that added the use of the slab allocator.  The

nir/constant_expressions: Rework Boolean handling

This commit contains three related changes.  First, we define boolN_t
for N = 8, 16, and 64 and move the definition of boolN_vec to the loop
with the other vec definitions.  Second, there's no reason why we need
the != 0 on the source because that happens implicitly when it's
converted to bool.  Third, for destinations, we use a signed integer
type and just do -(int)bool_val which will give us the 0/-1 behavior we
want and neatly scales to all bit widths.
