RFR(XS): JDK-8229375 Memory corruption in the implementation of the stack walk API

[dean.long at oracle.com]

It would be nice if we could detect problems like this automatically.  
Since this is an oop, we could figure out the field type at the given 
offset (slow).  Or keep around the type information that was given to 
STACKFRAMEINFO_FIELDS_DO and compute a {offset, size} tuple instead.
