[Mesa-dev] [PATCH 0/4] Begin some ir_dereference_array-of-a-vector rework

[Ian Romanick]

This is the first of three patch series that I'm going to send related
to reworking ir_dereference_array of vectors.  The final series end with
ir_dereference_array of vectors being completely removed from the IR.

The first series is a set of fixes for bugs that I discovered along the
way.  The first two are definitely candidates for the stable branches.
The second two might be, but I could be convinced either way.
