[PATCH] Fix warnings seen by clang in gcc/symbol-summary.h.

[Martin Liška]

Hi.

The patch is about missing argument to function call and
unused arguments in symbol-summary.h.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin

        argument a to the call of callback.
        (gt_ggc_mx): Mark arguments as unused.
        (gt_pch_nx): Likewise.
