Specifcally, for those that are curious, the bug is that the wrong PC
is stored when you're using WITH_REDIRECT so that the otherwise-useful
leak instruction address actually gets spammed with a local one from
inside libgc; instead, it now reaches back up another frame to get the
right one.

There's also a small improvement in the leak detection report code
that tries to look up the symbol for you using dladdr(3), but this
generally only works for library functions and not those in the
main executable; in any case, it's not worse than printing "unknown".
