[PATCH] Remove the gc.root's findCustomSafePoints mechanism

[Philip Reames]

Not quite sure what you're asking...

The behaviour of the ErlangGC did not change.  It's still using 
post-call labels.  (Or at least, I didn't *intend* to change it.  If I 
did, please point it out.)  It's just reaching that result through the 
(slightly modified) generic codepath.
