so the stuff in tree-ssa-forwprop:eliminate_unnecessary_casts in
autovect-branch is supposed to go under this tree-combiner pass as well, or
do you plan to merge it to mainline some time?
tree-ssa-forwprop:eliminate_unncessary_casts approach is
considered not appropriate for mainline (because
tree-combiner will take care of it.) so I do not plan to merge
it to mainline. I discussed this with tree-ssa folks when we
were chasing gzip performance. They preferred to wait for
tree-combiner instead of gaining gzip performance improvement
using this short term approach.
