PR c++/58407 - deprecated implicit copy ops.
gcc/c-family/
* c.opt (Wdeprecated-copy): New flag.
gcc/cp/
* call.c (build_over_call): Warn about deprecated trivial fns.
* class.c (classtype_has_user_copy_or_dtor): New.
(type_build_ctor_call): Check TREE_DEPRECATED.
(type_build_dtor_call): Likewise.

Add checks. Return bool. Handle -Wdeprecated-copy.
(mark_used): Use it.
* decl.c (grokdeclarator): Remove redundant checks.
* typeck2.c (build_functional_cast): Likewise.
* method.c (lazily_declare_fn): Mark deprecated copy ops.
* init.c (build_aggr_init): Only set TREE_USED if there are
side-effects.
libitm/
* beginend.cc (save): Disable -Werror=deprecated-copy.
