tools/syz-callgraph: add utility
ea45c1a 
syz-callgraph parses the Linux kernel source call graph
and prints how many times each function is called and its callers.
Run as:

  syz-callgraph -kernel_obj <path to kernel build directory built with clang>

The output format is:

  number-of-caller-functions/number-of-caller-files: function-name: callers

For example:
  005248/001316 _raw_spin_lock: ax25_get_socket tcf_block_insert gfs2_put_super lock_stripe_add nfsd4_lock
  005436/001339 _raw_spin_unlock: self_check_volume is_ses_using_iface gfs2_quota_cleanup blk_mq_mark_tag_wait
