Log message:
* tree-ssa-dom.c (simplify_cond_and_lookup_avail_expr): New function.
(find_equivalent_equality_comparison): Likewise.
(optimize_block): Remove code to build a == c equivalence after
seeing a == b and b == c. Remove code to walk backwards
though typecasts to record equivalences and move relevant parts
into find_equivalent_equality_comparison.
