We currently use the group->next pointer to iterate through the <group>
tags. This change them to be a type of field, so we can descend into
them while iterating, and then go back to the original position. Will be
useful when we want to decode <group>'s inside <group>'s, and when there
are more <field>'s after a <group> tag.

A gen_group (group in most of the code) can be of several types:
- instruction
- struct
- register
- group (?!?)
The <group> tag actually represents an array of elements. So at least
in our code, lets call it an array to avoid confusion with gen_group.

Normally, we haven't worried too much about stack sizes as Linux tends
to be fairly friendly towards large stacks. However, when running DXVK
apps under wine, we're suddenly subject to Windows' more stringent stack
limitations and can run out of space more easily. In particular, some
of the shaders in Elite Dangerous: Horizons have quite a few registers
and the arrays in split_virtual_grfs are large enough to blow a 1 MiB
stack leading to crashes during shader compilation.

A couple patches later in this series use the flag to avoid a few
thousand shader-db regresions on all vec4 platforms.
I'm not particularly enamored with the name of this flag. However, I
suspect the Intel vec4 backend is the only backend that will benefit
from it. Specifically, the cases where this helps are all cases where
we want to prevent nir_opt_algebraic from rearranging instructions to
create 3-source instructions, such as ffma and flrp, with additional
immediate value or uniform sources.
The earlier commit "intel/vec4: Try to emit a single load for multiple
3-src instruction operands" solves most of the problems caused by
additional immediate values, but the restrictions on register strides
that cause problems for uniforms and shader inputs persist.
