rb_profile_frames() causes segmentation fault

Bug #11851: rb_profile_frames() causes segmentation fault

ruby -v:
ruby 2.3.0dev (2015-12-20 trunk 53215) [x86_64-linux]
Backport:
2.0.0: DONTNEED, 2.1: DONTNEED, 2.2: DONTNEED
[ruby-core:72409]

Description

When the control frame stack contains an ifunc-frame, calling rb_profile_frames() causes a segmentation fault.

I've attached a patch that changes it to ignore ifunc frames as it did previously.
