Don't free dominators after sincos

2015-10-30 Thread Richard Sandiford
sincos has always freed dominators at the end, but AFAICT they should still be up-to-date. (In particular, gimple_purge_dead_eh_edges updates the information.) Tested on x86_64-linux-gnu, arm-linux-gnueabi and aarch64-linux-gnu. OK to install? Thanks, Richard gcc/ * tree-ssa-math-opts.
