Log:
    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.
