Make --prof_lazy log the addresses of shared libraries. Without those addresses,
the output of the tick processor is not very useful for node.js applications.

Address logging was disabled for --prof-lazy in r3154 for reasons that no longer
apply: the profiler is started on demand and hence looking up the addresses is
deferred until it's actually necessary.

The previous duplication is quite bad from an architectural point of
view. Furthermore, it messes up the output of --hydrogen-stats.

As remarked in a comment, there is still more unification work to do, but at
least this CL is a step in the right direction...

This allows Crankshaft to allow inlining of multiple different closures
that were all derived from the same shared function info. This pattern
appears when libraries provide generic closures that are used over and
over again at different call-sites.

This allows Crankshaft to generate monomorphic loads when the receiver
type is statically known even though the load site has polymorphic type

If a live range was split immediately before an instruction that required a

register/stack slot information of the preceeding live range rather than the one
that actually covers the safe-point.

Each map has a weak array of dependent codes, where the map tracks all the optimized codes that embed it.
Old space GC either clears the dead dependent codes from the array if the corresponding map is alive or deoptimizes the live dependent codes if the map is dead.
