* tree-flow.h (gimple_purge_all_dead_abnormal_call_edges): Declare.
* tree-cfg.c (gimple_purge_dead_abnormal_call_edges): Move around and
rewrite modelled on gimple_purge_dead_eh_edges.
(gimple_purge_all_dead_abnormal_call_edges): New function.
* tree-inline.c (expand_call_inline): Call gimple_purge_dead_eh_edges
directly instead of through gimple_purge_dead_abnormal_call_edges.
* tree-ssa-pre.c (need_ab_cleanup): New static variable.
(eliminate): Set bit in need_ab_cleanup for the basic block if we have
removed AB side-effects from one of its statements.
(init_pre): Initialize need_ab_cleanup.
(fini_pre): Purge dead abnormal call edges and clean up the CFG if bits
are set in need_ab_cleanup. Free need_ab_cleanup afterward.
