c2bfb4e93c add new instruction attribute called leaf 
An instruction is leaf if it has no rb_funcall inside.  In order to
check this property, we introduce stack canary which is a random
number collected at runtime.  Stack top is always filled with this
number and checked for stack smashing operations, when VM_CHECK_MODE.
