i965: Make INTEL_DEBUG=bat decode VS/CLIP/GS/SF/WM/CC_STATE on Gen4-5.

On Gen6+, we enable statistics all the time because they're necessary
to support various query object targets.  Turning them off would break
those queries.

Gen4-5 don't support those queries, so the statistics counters generally
aren't useful; we disabled them by default.  This patch disables them
altogether.

i965: Disable ARB_pipeline_statistics_query on Gen4-5.

We apparently enabled this on all platforms in Mesa 10.6.  However, it

flames with an "Unrecognized query target" unreachable() error if you
even attempt to use any of the new functionality.

This wasn't caught because the Piglit tests require OpenGL 3.0, which
Gen4-5 cannot support.  The extension spec does say 3.0 is required,
though I'm not sure why - it seems like 2.1 would work fine.

We could implement it anyway, but it's a little bit of a pain due to the
lack of hardware contexts (so we have to snapshot around batches).

Given that it's been 100% broken for two years and I haven't seen a bug
report about it, I'm not terribly inclined to care.  So, let it go.

nir: Embed the shader_info in the nir_shader again

Commit e1af20f18a86f52a9640faf2d4ff8a71b0a4fa9b changed the shader_info
from being embedded into being just a pointer.  The idea was that
sharing the shader_info between NIR and GLSL would be easier if it were
a pointer pointing to the same shader_info struct.  This, however, has
caused a few problems:

 1) There are many things which generate NIR without GLSL.  This means
    we have to support both NIR shaders which come from GLSL and ones
    that don't and need to have an info elsewhere.

 2) The solution to (1) raises all sorts of ownership issues which have
    to be resolved with ralloc_parent checks.

 3) Ever since 00620782c92100d77c660f9783504c6d80fa1d58, we've been
    using nir_gather_info to fill out the final shader_info.  Thanks to
    cloning and the above ownership issues, the nir_shader::info may not
    point back to the gl_shader anymore and so we have to do a copy of
    the shader_info from NIR back to GLSL anyway.

All of these issues go away if we just embed the shader_info in the
nir_shader.  There's a little downside of having to copy it back after
calling nir_gather_info but, as explained above, we have to do that
anyway.

swr: fix polygonmode for front==back

Rasterizer core only supports polygonmode front==back.  Add logic for
populating fillMode for the rasterizer only for that case correctly.
Provide enum conversion between mesa enums and core enums.

The core renders lines/points as tris. Previously, code would enable
stipple for polygonmode != FILL.  Modify stipple enable logic so that
this works correctly.

No regressions in vtk tests.
Fixes the following piglit tests:
pointsprite
gl-1.0-edgeflag-const

swr/rast: support polygonmode point

Add support for polygonmode point in the binner.  This is done by
splitting BinPostSetupPoints from BinPoints, so the earlier call can be
called from BinTriangles.  Setup has already been done at the time
BinPostSetupPoints needs to be called.

This checkin just adds support in the rasterizer.  A separate checkin
will add the appropriate driver support.

swr: move msaa resolve to generalized StoreTile

v3: list piglit tests fixed by this patch. Fixed typo Tim pointed out.
v2: Reword commit message to more closely adhere to community
guidelines.

This patch moves msaa resolve down into core/StoreTiles where the
surface format conversion routines are available.  The previous
"experimental" resolve was limited to 8-bit unsigned render targets.

This fixes a number of piglit msaa tests by adding resolve support for
all the render target formats we support.

Specifically:
layered-rendering/gl-layer-render: fail->pass
layered-rendering/gl-layer-render-storage: fail->pass
multisample-formats *[2,4,8,16] gl_arb_texture_rg: crash->pass
multisample-formats *[2,4,8,16] gl_ext_texture_snorm: crash->pass
multisample-formats *[2,4,8,16] gl_arb_texture_float: fail->pass
multisample-formats *[2,4,8,16] gl_arb_texture_rg-float: fail->pass

MSAA is still disabled by default, but can be enabled with
"export SWR_MSAA_MAX_COUNT=4" (1,2,4,8,16 are options)
The default is 0, which is disabled.

This patch improves the number of multisample-formats supported by swr,
and fixes several crashes currently in the 17.1 branch.  Therefore, it
should be considered for inclusion in the 17.1 stable release.  Being
disabled by default, it poses no risk to most users of swr.
