Speedup loop splitting SSA update

Since we never process loops with inner loops that have been split
we can delay SSA update until after the pass is done with the whole
loop, avoiding the O(function-size) work associated with it.

* tree-ssa-loop-split.cc (fix_loop_bb_probability): Do not
call update_ssa.
