re PR middle-end/45307 (Stores expanding to no RTL not removed by tree optimizers, Empty ctors/dtors not eliminated)
PR c++/45307
PR c++/17736
* cgraph.h (cgraph_only_called_directly_p,
cgraph_can_remove_if_no_direct_calls_and_refs_p): Handle
static cdtors.
* cgraphunit.c (cgraph_decide_is_function_needed): Static cdtors
are not needed.
(cgraph_finalize_function): Static cdtors are reachable.
(cgraph_mark_functions_to_output): Use cgraph_only_called_directly_p.
* gcc.dg/ipa/ctor-empty-1.c: Add testcase.
* g++.dg/tree-ssa/empty-2.C: Check that constructor got optimized out.
