Fix PR tree-optimization/19624
* Makefile.in (tree-ssa-pre.o): Add CFGLOOP_H.
* tree-ssa-pre.c: Add cfgloop.h.
Update comment.
(pre_stats): New member, constified.
(inserted_exprs): New static variable.
(NECESSARY): New macro.
(create_expression_by_pieces): Fold the expression, and
mark it as defaulting to not necessary. Also put in
inserted_exprs.
(fully_constant_expression): New function.
(insert_into_preds_of_block): Modify to not insert phis when we
are playing with induction variables.
Push phis onto the inserted_exprs vector, and mark them as not
necessary by default.
(insert_aux): Call fully_constant_expression on eprime.
If all edges produce the same value, mark it constant.
(mark_operand_necessary): New function.
(remove_dead_inserted_code): New function.
(init_pre): Init loop optimizer to get loop info.
(fini_pre): Free loop_optimizer, and inserted_exprs vec.
(execute_pre): Commit edge inserts, then remove dead code.
