Log:
PR tree-optimization/59519
* tree-vect-loop-manip.c (slpeel_update_phi_nodes_for_guard1): Don't
ICE if get_current_def (current_new_name) is already non-NULL, as long
as it is a phi result of some other phi in *new_exit_bb that has
the same argument.
* gcc.dg/vect/pr59519-1.c: New test.
* gcc.dg/vect/pr59519-2.c: New test.
