Generic varyings in TGSI were based on the value of VARYING_SLOT_TEX0, so VAR0
was always GENERIC[22] (with tessellation patches). Some drivers might not
be able to cope with that.
This commit defines a proper mapping, so that PNTC is GENERIC[8] and VAR0 is
GENERIC[9].

This enables a gallium driver not to care about the semantics of
ARB_sample_shading vs ARB_gpu_shader5 sample attributes. When
ARB_sample_shading-style sample shading is enabled, all of the fp inputs
are marked for interpolation at the sample location.

Commit c5d822dad9 added support for sample mask incorrectly. It became

In patches to follow, this will allow us to replace a lot of ad-hoc

With the exception of the changes to mtypes.h, this patch was

get a pointer to the dummy/placeholder program. We can't destroy that one
so just skip it. This only failed during context tear-down because
glDeleteProgramsARB() was already aware of dummy programs.

For ARB_color_buffer_float. Most hardware can't do it and st/mesa is
the perfect place for a fallback.
The exceptions are:
- r500 (vertex clamp only)
- nv50 (both)
- nvc0 (both)
- softpipe (both)
We also have to take into account that r300 can do CLAMPED vertex colors only,
while r600 can do UNCLAMPED vertex colors only. The difference can be expressed
with the two new CAPs.
This introduces an unspecified interpolation paramter that is only allowed for
color semantics, so a specified GLSL interpolation will override the ShadeModel
specified interpolation, but not vice-versa.
This fixes a lot of the interpolation tests in piglit.
