This series extends nir_algebraic/nir_search to support matching on arbitrary opcodes, and then uses it to implement constant reassociation similar to what we already do in opt_algebraic. I haven't piglit tested this yet, although I did verify that it did the right thing in a few simple tests. Note that for pigliting it might be wise to turn off opt_algebraic since in some cases (but not all) it will do the same optimization so we don't get a chance to exercise the code.
