gallium: add bits for clipping points as tris (d3d-style)

OpenGL does whole-point clipping, that is a large point is either fully
clipped or fully unclipped (the latter means it may extend beyond the
viewport as long as the center is inside the viewport). d3d9 (d3d10 has
no large points) however requires points to be clipped after they are
expanded to a rectangle. (Note some IHVs are known to ignore GL rules at
least with some hw/drivers.)
Hence add a rasterizer bit indicating which way points should be clipped
(some drivers probably will always ignore this), and add the draw interaction
this requires. Drivers wanting to support this and using draw must support
large points on their own as draw doesn't implement vp clipping on the
expanded points (it potentially could but the complexity doesn't seem
warranted), and the driver needs to do viewport scissoring on such points.

llvmpipe: do constant buffer bounds checking in shaders

It's possible to bind a smaller buffer as a constant buffer, than
what the shader actually uses/requires. This could cause nasty
crashes. This patch adds the architecture to pass the maximum
allowable constant buffer index to the jit to let it make
sure that the constant buffer indices are always within bounds.
The behavior follows the d3d10 spec, which says the overflow
should always return all zeros, and overflow is only defined
as access beyond the size of the currently bound buffer. Accesses
beyond the declared shader constant register size are not
considered an overflow and expected to return garbage but consistent
garbage (we follow the behavior which some wlk tests expect which
is to return the actual values from the bound buffer).

mesa: Add COMPRESSED_RGBA_S3TC_DXT1_EXT to COMPRESSED_TEXTURE_FORMATS for GLES

The ES and desktop GL specs diverge here.  Yay!

In desktop OpenGL, the driver can perform online compression of
uncompressed texture data.  GL_NUM_COMPRESSED_TEXTURE_FORMATS and
GL_COMPRESSED_TEXTURE_FORMATS give the application a list of formats
that it could ask the driver to compress with some expectation of
quality.  The GL_ARB_texture_compression spec calls this "suitable for
general-purpose usage."  As noted above, this means
GL_COMPRESSED_RGBA_S3TC_DXT1_EXT is not included in the list.

In OpenGL ES, the driver never performs compression.
GL_NUM_COMPRESSED_TEXTURE_FORMATS and GL_COMPRESSED_TEXTURE_FORMATS give
the application a list of formats that the driver can receive from the
application.  It is the *complete* list of formats.  The
GL_EXT_texture_compression_s3tc spec says:

    "New State for OpenGL ES 2.0.25 and 3.0.2 Specifications

        The queries for NUM_COMPRESSED_TEXTURE_FORMATS and
        COMPRESSED_TEXTURE_FORMATS include COMPRESSED_RGB_S3TC_DXT1_EXT,
        COMPRESSED_RGBA_S3TC_DXT1_EXT, COMPRESSED_RGBA_S3TC_DXT3_EXT,
        and COMPRESSED_RGBA_S3TC_DXT5_EXT."

ilo: handle NULL renderbuffers correctly

Renderbuffers may be NULL since 9baa45f78b8ca7d66280e36009b6a685055d7cd6.

ilo: disable HiZ for misaligned levels

We need to disable HiZ for non-8x4 aligned levels, except for level 0, layer
0.  For the very first layer we can adjust Width and Height fields of
3DSTATE_DEPTH_BUFFER to make it aligned.

Specifically, add ILO_TEXTURE_HIZ and set the flag only for properly aligned
levels.  ilo_texture_can_enable_hiz() is updated to check for the flag.

In tex_layout_validate(), align the depth bo to 8x4 so that we can adjust
Width/Height of 3DSTATE_DEPTH_BUFFER without introducing out-of-bound access.

Finally in rectlist blitter, add the ability to adjust 3DSTATE_DEPTH_BUFFER.

ilo: use a helper to determine if HiZ is enabled

to ilo_texture_can_enable_hiz().

ilo: decide on hiz first in texture allocation

Add tex_layout_init_hiz() before tex_layout_init_format() to decide whether
HiZ should be enabled.

On GEN6, because of layer offsetting, HiZ is enabled only when the texture is
non-mipmapped and non-array.  PIPE_USAGE_STAGING is also taken as a hint to
disable HiZ.

ilo: emit gen7_wa_pipe_control_wm_max_threads_stall on Haswell

glsl: Use a new foreach_two_lists macro for walking two lists at once.

When handling function calls, we often want to walk through the list of
formal parameters and list of actual parameters at the same time.
(Both are guaranteed to be the same length.)

Previously, we used a pattern of:

   exec_list_iterator 1st_iter = <1st list>.iterator();
   foreach_iter(exec_list_iterator, 2nd_iter, <2nd list>) {
      ...
      1st_iter.next();
   }

This was awkward, since you had to manually iterate through one of
the two lists.

This patch introduces a foreach_two_lists macro which safely walks
through two lists at the same time, so you can simply do:

   foreach_two_lists(1st_node, <1st list>, 2nd_node, <2nd list>) {
      ...
