This is the reason the declaration member existed in the reference
visitor, but I didn't copy the code from structure splitting that
avoided setting it.
This wasn't currently a problem, because we don't allow splitting of
in/out variables. But that would be nice to change some day.

This was carried over from structure splitting, without thinking about
whether the name still made sense in this context.

Ken noted that some of the "actual work" was happening in the caller
of this class.

Ken noted this in a review of this patch that I pushed early.

Vinson reported that we failed to initialize this, which would lead to
all kinds of crashes if we actually used it. Since we don't use it,
we may as well just delete the broken code.

This should fit in well with our lower_mat_op_to_vec code: now, in
addition to having expressions on each column of a matrix, we also
split the columns to separate variables so they can be tracked
individually by the copy propagation, dead code, and other passes.
This optimizes out some more code generation in unigine and gstreamer
shaders.

I've had this code laying around almost done for a long time. The
idea is like opt_structure_splitting, that we've got a bunch of
transforms at the GLSL IR level that only understand scalars and
vectors, which just skip complicated dereferences. While driver
backends may manage some optimization after they split matrices up
themselves, it would be better to bring all of our optimization to
bear on the problem.
While I wasn't expecting changes quite yet, a few programs end up
winning: a gstreamer convolution shader, and the Humus dynamic
branching demo:

3/2148 programs affected (0.1%)
1498 -> 1410 instructions in affected programs (5.9% reduction)
