called from within a loop or not.  In the past we lost the
information if a call site went megamorphic before a lazily
compiled callee was called for the first time.  Now we track
that correctly (this is an issue that affects richards).
We still don't manage to track the in-loop state through a
constructor call, since constructor calls use LoadICs instead
of CallICs.  This issue affects delta-blue.  So in this patch
we assume that lazy compilations that don't happen through a
CallIC happen from inside a loop.  I have an idea to fix this
but this patch is big enough already.
With our improved tracking of in-loop state I have switched
off the inlining of in-object loads for code that is not in
a loop.  This benefits compile speed.  One issue is that
eagerly compiled code now doesn't get the in-object loads
inlined.  We need to eagerly compile less code to fix this.
