• ext/objspace/object_tracing.c: fix a bug reported at
  "[ruby-core:55182] [ruby-trunk - Bug #8456][Open] Sugfault in Ruby Head"
  Care about the case TracePoint#path #=> `nil'.
• ext/objspace/object_tracing.c: add two new methods:
• ObjectSpace.allocation_class_path(o)
• ObjectSpace.allocation_method_id(o)
  They are not useful for Object.new because they are always
  "Class" and :new.
  To trace more useful information, we need to maintain call-tree
  using call/return hooks, which is implemented by
  ll-prof http://sunagae.net/wiki/doku.php?id=software:llprof
• test/objspace/test_objspace.rb: add a test.
