[PATCH] Limit path splitting to loops we optimize for speed
* doc/invoke.texi (-O2 options): Remove -fsplit-paths.
(-O3 options): Add -fsplit-paths.
* gimple-ssa-split-paths.c: Include predict.h
(split_paths): Only split paths in a loop that should be
optimized for speed.
* opts.c (default_options_table): Move -fsplit-paths from -O2 to
-O3.
* gcc.dg/tree-ssa/split-path-1.c: Explicitly ask for path
splitting optimizations.
