Enhancement of call graph API
* cgraph.h (expand_thunk): New argument added.
(address_taken_from_non_vtable_p): New global function.
* ipa-visibility.c (address_taken_from_non_vtable_p): Likewise.
* cgraphclones.c (duplicate_thunk_for_node): Argument added to call.
* cgraphunit.c (analyze_function): Likewise.
(assemble_thunks_and_aliases): Argument added to call.
(expand_thunk): New argument forces to produce GIMPLE thunk.
