vc4: Add support for texture border color.

One spot in the docs says that it's stored at a miplevel just beyond the
last miplevel, which was scary.  But really, you just load it as the R
coordinate (which conflicts with cubemaps, but you don't do border
clamping on cubes).

vc4: Add the necessary stubs for occlusion queries.

We have to expose them for GL 2.0, but we just always return a value of 0.
We should be advertising 0 query bits instead of 64, but gallium doesn't
have plumbing for that yet.  At least this stops the segfaults.

vc4: Optimize out silly SUBs of 0.

Drops instructions on vs-temp-array-mat4-index-col-row-wr.shader_test,
which I was looking at because it's failing to register allocate.

vc4: Dump constant uniform values in VC4_DEBUG=qir.

Definitely helps when trying to understand and optimize a program.

vc4: Turn a SEL_X_Y(x, 0) into SEL_X_0(x).

This may reduce register pressure and uniform counts.  Drops a bunch of 0
uniform loads on vs-temp-array-mat4-index-col-row-wr.shader_test, which is
failing to register allocate.

vc4: Add support for texture cube maps.

It's not passing some of the piglit tests, because it looks like at small
miplevels some contents from surrounding faces are getting filtered in at
the corners.  It does get 7 new tests passing.

vc4: Rename the slice's size0.

In the other related fields, "0" refers to the size of the first miplevel,
while this is a field in a slice.  The other implicit slices we have
(cubemap layers) don't vary in size compared to the first one.

vc4: Stop trying to reuse temporaries that store uniform values.

Almost always, the MOV will get copy propagated out.  Even if it doesn't,
it's probably better to just reload the uniform at next use (to reduce
register pressure) rather than try to save instruction count.

I was looking at this because in the presence of texturing (which calls
add_uniform() directly to get the uniform load forced into the
instruction) the c->uniform_contents indices don't match 1:1 with the
temporary qregs.

mesa: Replace a priori knowledge of gcc builtins with configure tests.

Presumbly this will let clang and other compilers use the built-ins as
well.

Notice two changes specifically:
   - in _mesa_next_pow_two_64(), always use __builtin_clzll and add a
     static assertion that this is safe.
   - in macros.h, remove the clang-specific definition since it should
     be able to detect __builtin_unreachable in configure.

i965: Emit ELSE/ENDIF JIP with type D on Gen 7.

The spec says the type must be W (JIP is 16-bits after all), but we've
been emitting it with a UD type all along and have experienced no
adverse effects. Changing the type to D allows ELSE and ENDIF

We're currently emitting compactable control flow instruction the wrong
types, preventing their compaction. The next patch will fix this and
actually enable compaction.

which is a gl_vertex_attrib_array structure, not a gl_client_array.

The offsets of all fields happened to be the same in both structures, at

both structures start with the same fields, in the same order.

"Enabled" is dicier: there are different fields before it in both
structures, including pointer sized values which might need special

vc4: Compute max_index instead of trusting the rest of userspace.

max_index was coming from either the user telling us as part of
glDrawRangeElements, or from an incidental calculation as part of some
sort of primitive conversion fallback.  Sometimes, it was just set to the
default "I don't know" ~0 value.

If it wasn't set to the actual max index, then the kernel would reject the
draw call for allowing out-of-bounds VBO reads.  So, compute the max index
from the sizes of the VBOs, which isn't too expensive (unlike mapping and
reading the index buffer) and is reliable.

Fixes piglit vao-element-array-buffer.

vc4: Move shader record setup before the draw call.

The flush only happens after both are written, so we can do them in either
