re PR middle-end/16585 (current_function_has_computed_jump incorrectly changed in make_edges)
PR middle-end/16585
* cfgbuild.c (make_edges): Do not clear or set
current_function_has_computed_jump.
* function.h (struct function): Remove the has_computed_jump field.
(current_function_has_computed_jump): Do not define.
* sched-rgn.c (is_cfg_nonregular): Return true if a basic block ends
in a computed jump. Ignore current_function_has_computed_jump.
