PR c++/53551 - -Wunused-local-typedefs misses uses
We don't record the use of a typedef when it's used through a
typename. Fixed thus.
Tested on x86_64-unknown-linux-gnu against trunk.
gcc/cp/
* decl.c (make_typename_type): Record the use of typedefs.
gcc/testsuite/
* g++.dg/warn/Wunused-local-typedefs-2.C: New test.
