re PR tree-optimization/82060 (ICE in refs_may_alias_p_1 with devirtualization enabled)

PR tree-optimization/82060
* tree-ssa-pre.c (eliminate_dom_walker::before_dom_children):
Move devirtualization after stmt folding and before EH/AB/noreturn
cleanup to get the stmt refs canonicalized. Use a bool instead
of gimple_modified_p since that doesn't work for NOPs. Schedule
NOPs generated by folding for removal.
* g++.dg/torture/pr82060.C: New testcase.
