perf annotate: Pass function descriptor to its instruction parsing routines
We need that to figure out if jumps have targets in a different function. E.g. _cpp_lex_token(), in /usr/libexec/gcc/x86_64-redhat-linux/5.3.1/cc1 has a line like this: jne c469be <cpp_named_operator2name@@Base+0xa72> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-ris0ioziyp469pofpzix2atb@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
