Add a small inline function doing the casting - this is to make sure

does not make tgsi_sampler parameters const in vfuncs themselves for
now - probably llvmpipe would need looking at before making such a

As of a10d4937, we would really like things associated with an instruction
to be allocated out of that instruction and not out of the shader. In
particular, you should be passing the instruction that will ultimately be
holding the source into nir_src_copy rather than an arbitrary memory
context.
We also change the prototypes of nir_dest_copy and nir_alu_src/dest_copy to
explicitly take an instruction so we catch this earlier in the future.

We copy the output, make the old output the temporary, and give the
temporary a new name. The copy keeps the pointer to the old name. This
works just fine up until the point where we lower things to SSA and delete
the old variable and, with it, the name. Instead, we should re-parent to
the copy.

This makes it possible for NIR shaders to know the number of output
vertices and the number of invocations. Drivers could also access
these directly without going through gl_program.
We should probably add InputType and OutputType here too, but currently
those are stored as GL_* enums, and I wanted to avoid using those in
NIR, as I suspect Vulkan/SPIR-V will use different enums. (We should
probably make our own.)
We could add VerticesIn, but it's easily computable from the input
topology, so I'm not sure whether it's worth it. It's also currently
not stored in gl_shader (only gl_shader_program), which would require
changes to the glsl_to_nir interface or require us to store it there.
This is a bit of duplication of data...ideally, we would factor these
substructs out of gl_program, gl_shader_program, and nir_shader, creating
a gl_geometry_info class...but it would need to go in a new place (in
src/glsl?) that isn't mtypes.h nor nir.h.

Previously the result of the complicated clamp() expression just dropped
on the floor: clamp does not modify any of its parameters. Looking at
the surrounding code, I believe this is supposed to modify the value of
tex_coord.
This change (along with a change to avoid the use of
brw_blorp_framebuffer) does not affect any existing piglit tests. I'm
not sure what this clamp is trying to accomplish, so I'm not sure how to
write a test to exercise this path.
I also noticed another bug in this code. There is no way the array
texture case could possibly work. This will generate code for the
TEXEL_FETCH macro like:
#define TEXEL_FETCH(coord) texelFetch(texSampler, ivec3(coord), sample_map[int(2 * fract(coord.x))]);
Since the coord parameter of this macro is a vec2 at all invocations, no
expansion of this macro will even compile.
