PR tree-optimization/45453
* cgraphunit.c (cgraph_finalize_function): Consider comdat & external
virtual functions are reachable.
* ipa-inline.c (cgraph_clone_inlined_nodes): Likewise.
* ipa.c (cgraph_remove_unreachable_nodes): Likewise.
* ipa-prop.c (ipa_modify_formal_parameters): Clear DECL_VIRTUAL_P
when modifying function.
* g++.dg/tree-ssa/pr45453.C: New testcase.
