re PR middle-end/17278 (8% C++ compile-time regression in comparison with 3.4.1 at -O1 optimization level)
PR middle-end/17278
* opts.c (decode_options): Move flag_thread_jumps from -O1 and
higher to -O2 and higher. Likewise for tree PRE.
* tree-ssa-dom.c (tree_ssa_dominator_optimize): Only iterate at -O2
and better.
