re PR middle-end/36550 (Wrong "may be used uninitialized" warning (conditional PHIs))
PR tree-optimization/36550
* tree-ssa-threadupdate.c (count_stmts_and_phis_in_block): New.
(mark_threaded_blocks): Rewrite code to avoid block copying when
optimizing for size. Don't pessimize blocks which will be
copied, but all the statements will be dead.
PR tree-optimization/36550
* gcc.dg/tree-ssa/pr36550.c: New test.
