perf annotate: Mark jumps to outher functions with the call arrow

Things like this in _cpp_lex_token (gcc's cc1 program):

     cpp_named_operator2name@@Base+0xa72

Point to a place that is after the cpp_named_operator2name boundaries,
i.e.  in the ELF symbol table for cc1 cpp_named_operator2name is marked
as being 32-bytes long, but it in fact is much larger than that, so we
seem to need a symbols__find() routine that looks for >= current->start
and  < next_symbol->start, possibly just for C++ objects?

For now lets just make some progress by marking jumps to outside the
current function as call like.

Actual navigation will come next, with further understanding of how the
symbol searching and disassembly should be done.
