src/cpu/x86/vm/frame_x86.cpp
     I like that sender_sp, sender_pc, and saved_fp are now declared
     together and set together. Much more clean.

Thumbs up.

P.S.
It does seem a little strange that the 'link_offset' enum is
defined in a section of src/cpu/x86/vm/frame_x86.hpp that is
commented as "C++ interpreter".
