re PR ipa/65610 (Compare debug failure with -g3 -fsanitize=undefined -fno-sanitize=vptr -O3)
PR ipa/65610
* ipa-utils.h (inlined_polymorphic_ctor_dtor_block_p): Declare.
* ipa-polymorphic-call.c (inlined_polymorphic_ctor_dtor_block_p): New
function.
(decl_maybe_in_construction_p, noncall_stmt_may_be_vtbl_ptr_store):
Use it.
* ipa-prop.c (param_type_may_change_p): Likewise.
* tree-ssa-live.c: Include ipa-utils.h and its dependencies.
(remove_unused_scope_block_p): Add in_ctor_dtor_block
argument. Before inlining, preserve
inlined_polymorphic_ctor_dtor_block_p blocks and the outermost block
with FUNCTION_DECL BLOCK_ABSTRACT_ORIGIN inside of them. Adjust
recursive calls.
(remove_unused_locals): Adjust remove_unused_scope_block_p caller.
* g++.dg/ubsan/pr65610.C: New test.
