 FloatOut: Allow floating through breakpoint ticks

 I believe this is actually a completely valid thing to do, despite the
 arguments put forth in #10052. All that was missing was logic in
 SetLevels to correctly substitute the cloned binders into the
 breakpoint's free variable list.

 This is a prerequisite for enabling StaticPointer support in the
 interpreter.

 Test Plan: Validate
