9fe00836f7 fix stack mapping code to do as many passes as necessary 
Previously, we had been doing exactly two passes over the event log to
caculate the stack object reference map at each trace point.  It turns
out the correct number of passes depends on how many incorrect
assumptions we make about what the stack looks like at instructions with
multiple predecessors (i.e. targets of jumps and branches).

Each time we detect we've made one or more incorrect assumptions during
a pass, we must do another pass to correct those assumptions.  That pass
may in turn reveal further incorrect assumptions, and so on.

c1f3d28d24 Fixes dynamic symbol loading bug on Mac OS X. 
On OS X, when you call dlopen() on a null library, and then call dlsym(),
the most recently loaded symbols are always used, no matter what flags
we seem to pass to dlopen().  The solution is to explicitly find the name
of the running executable, and open that as a library.
