Enable -Wunused-local-typedefs when -Wall or -Wunused is on
Now that the libstdc++ testsuite is run with -ftrack-macro-location by
default, this patch triggers the -Wunused-local-typedefs warning when
-Wunused (and -Wall) is turned on.
The patch has been reviewed and accepted[1] a while ago, but was waiting
for the -ftrack-macro-expansion work to go in first.
Bootstrapped and tested again on x86_64-unknown-linux-gnu against
trunk.
Applied to the mainline.

gcc/
* opts.c (finish_options): Activate -Wunused-local-typedefs if
-Wunused is activated.
* doc/invoke.texi: Update blurb of -Wunused-local-typedefs.
