re PR tree-optimization/48739 (ICE in check_loop_closed_ssa_use() with "-ftree-parallelize-loops=2 -fno-tree-dominator-opts")
PR tree-optimization/48739
* tree-ssa.c: Include cfgloop.h.
(execute_update_addresses_taken): When updating ssa, if in
loop closed SSA form, call rewrite_into_loop_closed_ssa instead of
update_ssa.
* Makefile.in (tree-ssa.o): Depend on $(CFGLOOP_H).
* gcc.dg/pr48739-1.c: New test.
* gcc.dg/pr48739-2.c: New test.
