Functional change in which way half-way cases are rounded from towards
positive-infinity to even. The spec says "the passed value is rounded to
the nearest integer". Removes another case of bad half-up rounding.
gcc actually generates this for us now that we use -fno-math-errno
(which is weird, since lrintf()/lrint() don't set errno) but clang still
does not. Presumably helps MSVC as well.
Reduced .text size by 8.5k with gcc before -fno-math-errno.

Fixes a giant pile of GCC warnings:
builtin_types.cpp:60:1: warning: missing initializer for member 'glsl_struct_field::stream' [-Wmissing-field-initializers]
I had to add a default constructor because a non-default constructor
was added. Otherwise the only constructor would be the one with
parameters, and all the plases like
glsl_struct_field foo;
would fail to compile.
I wanted to do this in two patches. All of the initializers of
glsl_struct_field structures had to be converted to use the
constructor because C++ apparently forces you to do one or the other:
builtin_types.cpp:61:1: error: could not convert '{glsl_type::float_type, "near", -1, 0, 0, 0, GLSL_MATRIX_LAYOUT_INHERITED, 0, -1}' from '<brace-enclosed initializer list>' to 'glsl_struct_field'

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

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.

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.
