c++: Don't emit deprecated/unavailable attribute diagnostics when creating cdtor thunks [PR116678]
Another spot where we mark_used a function (in this case ctor or dtor)
even when it is just artificially used inside of thunks (emitted on mingw
with -Os for the testcase).

PR c++/116678
* optimize.cc: Include decl.h.
(maybe_thunk_body): Temporarily change deprecated_state to
UNAVAILABLE_DEPRECATED_SUPPRESS.
* g++.dg/warn/deprecated-20.C: New test.
