This can probably be reduced even further by moving this logic to the
scissor state update or just removing the logic entirely, but I don't
trust myself in radeon quite that much.
It's past time, and it was going to get in the way of the renderbuffer
mapping refactor. We dropped all the other DRI1 drivers for this
release, and I can't imagine anybody supporting DRI1 radeon classic in
a new release of Mesa.
Diff produced by treating kernel_mm as true, deleting the DRI1 paths
that produce kernel_mm false, and deleting code.
They have been superseded by the gallium equivalents.

These are effectively doing type->get_base_type()->base_type, which is
equivalent to type->base_type. Just use that, as it's simpler.

And not all existing queries. The only reason we have that list is to be able
to suspend and resume the active ones.
This reduces looping over queries when suspending and resuming.
The queries no longer have to track some of their states.
We weren't setting TEX_SEM_WAIT on instructions that read the value of a
TEX instruction and also wrote the same register as the TEX instruction.
This is the sequence we were miscompiling:
1: TEX temp[0], input[2].xy__, 2D[0]
...
16: src0.xyz = temp[22], src1.xyz = temp[0], src2.xyz = temp[19]
MAD temp[0].xyz, src0.xxx, src1.xyz, src2.xxx

This required the following changes:
- WM setup now makes the appropriate set of barycentric coordinates
(perspective vs. noperspective) available to the fragment shader,
based on whether the shader requires perspective interpolation,
noperspective interpolation, both, or neither.
- The fragment shader backend now uses the appropriate set of
barycentric coordiantes when interpolating, based on the
interpolation mode returned by
ir_variable::determine_interpolation_mode().
- SF setup now uses gl_fragment_program::InterpQualifier to determine
which attributes are to be flat shaded (as opposed to the old logic,
which only flat shaded colors).
- CLIP setup now ensures that the clipper outputs non-perspective
barycentric coordinates when they are needed by the fragment shader.
Fixes the remaining piglit tests of interpolation qualifiers that were
failing:
- interpolation-flat-*-smooth-none
- interpolation-flat-other-flat-none
- interpolation-noperspective-*
- interpolation-smooth-gl_*Color-flat-*

The name was misleading. The actual effect of the bit is to cause
the clipper to emit *non-perspective* barycentric coordinate
information (which is only needed when doing noperspective
interpolation).

This patch changes how fs_visitor::emit_general_interpolation()
decides what kind of interpolation to do. Previously, it used the
shade model to determine how to interpolate colors, and used smooth
interpolation on everything else. Now it uses
ir_variable::determine_interpolation_mode(), so that it respects GLSL
1.30 interpolation qualifiers.
Fixes piglit tests interpolation-flat-*-smooth-{distance,fixed,vertex}
and interpolation-flat-other-flat-{distance,fixed,vertex}.

This patch modifies the fragment shader back-end so that instead of
using a single delta_x/delta_y register pair to store barycentric
coordinates, it uses an array of such register pairs, one for each
possible intepolation mode.
When setting up the WM, we intstruct it to only provide the
barycentric coordinates that are actually needed by the fragment
shader--that is computed by brw_compute_barycentric_interp_modes().
Currently this function returns just
BRW_WM_PERSPECTIVE_PIXEL_BARYCENTRIC, because this is the only
interpolation mode we support. However, that will change in a later
patch.

This patch modifies the special case in
fs_visitor::split_virtual_grfs() that prevents splitting from being
applied to the delta_x/delta_y register pair (this register pair needs
to remain contiguous so that it can be used by the PLN instruction).
When gen>=6, this register pair is in a fixed location, not a virtual
register, so it was in no danger of being split. And
split_virtual_grfs' attempt not to split it was preventing some other
unrelated register from being split.

This function determines how a variable should be interpolated based
both on interpolation qualifiers and the current shade model.

Previously, we treated the 'smooth' qualifier as equivalent to no
qualifier at all. However, this is incorrect for the built-in color
variables (gl_FrontColor, gl_BackColor, gl_FrontSecondaryColor, and
gl_BackSecondaryColor). For those variables, if there is no qualifier
at all, interpolation should be flat if the shade model is GL_FLAT,
and smooth if the shade model is GL_SMOOTH.
To make this possible, I added a new value to the
glsl_interp_qualifier enum, INTERP_QUALIFIER_NONE.

This patch makes GLSL interpolation qualifiers visible to drivers via
the array InterpQualifier[] in gl_fragment_program, so that they can
easily be used by driver back-ends to select the correct interpolation
mode.
Previous to this patch, the GLSL compiler was using the enum
ir_variable_interpolation to represent interpolation types. Rather
than make a duplicate enum in core mesa to represent the same thing, I
moved the enum into mtypes.h and renamed it to be more consistent with
the other enums defined there.

Without this it's possible to wind up in a draw call with the
glBegin/End VBO still in a mapped state. This is a problem for
the SVGA3D driver and probably not good for other HW drivers.
Now that texture borders are gone, we never need to allocate our
textures through non-miptrees, which simplifies some irritating paths.

This replaces software rendering of textures with the deprecated
1-pixel border (which is always bad, since mipmapping is rather broken
in swrast, and GLSL 1.30 is unsupported) with hardware rendering that
just pretends there was never a border (so you have potential seams on
apps that actually intentionally used the 1-pixel borders, but correct
rendering otherwise).
This doesn't regress any piglit tests on gen6 (since the texwrap
border/bordercolor cases already failed due to broken border color
handling), but regresses texwrap border cases on original gen4 since
those end up sampling the border color instead of the border pixels.
It's a small price to pay for not thinking about texture borders any
more.
