* cfgloopanal.c (get_loop_hot_path): New function.
* tree-ssa-lop-ivcanon.c (struct loop_size): Add CONSTANT_IV,
NUM_NON_PURE_CALLS_ON_HOT_PATH, NUM_PURE_CALLS_ON_HOT_PATH,
NUM_BRANCHES_ON_HOT_PATH.
(tree_estimate_loop_size): Compute the new values.
(try_unroll_loop_completely): Disable unrolling of loops with only
calls or too many branches.
(tree_unroll_loops_completely): Deal also with outer loops of hot loops.
* cfgloop.h (get_loop_hot_path): Declare.
* params.def (PARAM_MAX_PEEL_BRANCHES): New parameters.
* invoke.texi (max-peel-branches): Document.
* gcc.dg/tree-ssa/loop-1.c: Make to look like a good unroling candidate still.
* gcc.dg/tree-ssa/loop-23.c: Likewise.
* gcc.dg/tree-ssa/cunroll-1.c: Unrolling now happens early.
* gcc.dg/tree-prof/unroll-1.c: Remove confused dg-options.
