When the NIR-vec4 pass is enabled, handles uniform and GRF array access
on ARB_vertex_program like it is done on vertex shaders.
When the old IR-vec4 pass is used, emit_program_code() emits pull constant
loads directly instead of using relative addressing, hence to call to
move_uniform_array_access_to_pull_constants() is not needed and it is enough
to call to split_uniform_registers().
The patch also calls to move_grf_array_access_to_scratch() like it is
done for shaders, however I suspect this is a no-op for vertex programs and
we could remove it.

The implementation takes into account that on ARB_vertex_program
only a single nir variable is generated to support all the uniform data.

So the implementation is independent of GLSL IR and the visit methods of the
gen6 GS visitor. This way we will be able to reuse that implementation directly
from the NIR vec4 backend.

Outputs from the vertex shader become array inputs in the geomtry shader,
but the arrays are interleaved, so we need to map our inputs accordingly.

Avoid copying an overwritten swizzle, use the original values.
Example:
Former swizzle[] = xyzw
src->swizzle[] = zyxx
The expected output swizzle = zyxx but if we reuse swizzle in the loop,
then output swizzle would be zyzz.

Uses the nir structure to get all the info needed (sources,
dest reg, etc), and then it uses the common
vec4_visitor::emit_texture to emit the final code.

Splitted in two. The emission is moved to a new vec4_visitor

This is useful for the upcoming texture support in NIR->vec4 pass,
as we found several cases where the brw_type is available, but not
the glsl_type.
Without this new constructor, the alternative would be:
dst_reg reg(MRF, <reg>)
reg.type = <brw_type>
reg.writemask = <mask>
Adding a new constructor makes code easier to read.

The is_high_sample() method is currently accessible only in the implementation of
vec4_visitor. Since we need to reuse it in the upcoming NIR->vec4 pass, lets make
it a method of the class instead.
