With this patch, the svga shader type will be saved in the shader variant,
and there is no need to pass in the shader type to the define/destroy
variant functions.

svga_destroy_shader_variant() itself flushes and retries the command
if there's a failure. So no need for the callers to do it. Other
callers of the function were already ignoring the return value.
This also fixes a corner-case double-free reported by Coverity
(and reported by Dave Airlie).
Tested with various OpenGL apps.

Setting GL_POINT_SPRITE_COORD_ORIGIN to GL_LOWER_LEFT did not work for
vgpu9. We can use the rasterizer sprite_coord_enable bitfield as-is.
We need to index into it using the TGSI semantic index, not the
register index.
This fixes the Piglit fbo-gl_pointcoord and glsl-fs-pointcoord tests.
Testing done: Piglit, Mesa sprite demos

In some cases, We do shadow comparison cases in the fragment shader
instead of with texture sampler state. But when we do so, we must
disable the shadow comparison test in the sampler state. As it
was, we were doing the comparison twice, which resulted in nonsense.
Also, we had the texcoord and texel value swapped in the comparison
instruction.
Fixes about 38 Piglit tex-miplevel-selection tests.

The device doesn't directly support this feature so we implement it with
additional shader code which sets the color output(s) w component to
1.0 (or max_int or max_uint).
Fixes 16 Piglit ext_framebuffer_multisample/*alpha-to-one* tests.
v2: only support unorm/float buffers, not int/uint, per Roland.

Sometimes, converting unnormalized coordinates to normalized
coordinates requires an epsilon value to produce the right texels with
nearest filtering. Adding 0.0001 to the coordinates when the min/mag
filter is nearest fixes the issue.

Previously, we looked at the bound textures (via the pipe_sampler_views)
to determine texture dimensions (1D/2D/3D/etc) and datatype (float vs.
int). But this could fail in out of memory conditions. If we failed to
allocate a texture and didn't create a pipe_sampler_view, we'd default
to using 0 (PIPE_BUFFER) as the texture type. This led to device errors
because of inconsistent shader code.
This change relies on all TGSI shaders having an SVIEW declaration for
each SAMP declaration. The previous patch series does that.

Examine the fragment shader to try to detect TGSI shaders which use
"MOV OUT[0], CONST[i]" to write a constant value for the fragment color.
In this case, all fragments will have the same color (unless blending is
enabled).
This is a common case for OpenGL code such as: glColor(), glBegin(),
glVertex(), ..., glEnd() when lighting/fog/etc are disabled. In this
case, the Mesa/gallium state tracker actually generates a simple
"MOV OUT[0], CONST[i]" fragment shader.
This will be used by the next commit to avoid provoking vertex conversion
(creating/rewriting an index buffer) when drawing flat-shaded primitives.
