glsl: Convert lower_clip_distance_visitor to be an ir_rvalue_visitor
Right now the lower_clip_distance_visitor lowers variable indexing into
gl_ClipDistance into variable indexing into both the array
gl_ClipDistanceMESA and the vectors of that array. For example,
gl_ClipDistance[i] = f;
becomes
gl_ClipDistanceMESA[i >> 2][i & 3] = f;
However, variable indexing into vectors using ir_dereference_array is
being removed. Instead, ir_expression with ir_triop_vector_insert will
be used. The above code will become
gl_ClipDistanceMESA[i >> 2] =
vector_insert(gl_ClipDistanceMESA[i >> 2], i & 3, f);
In order to do this, an ir_rvalue_visitor will need to be used. This
commit is really just a refactor to get ready for that.
v4: Split the least amount of refactor from the rest of the code
changes.
