Code objects might be connected by static calls and these references
were not included into the profile. This lead to some objects being
unreachable from the root.
This CL also adds a test which computes dominators for all nodes
in the snapshot (this in turn verifies that there are no
unreachable nodes).

Exposing this functionality makes it possible to use this logic in Dart DevTools.
This CL also includes some renames that make the code more readable. When there are both `ProgramInfoNode`s and `CallGraphNode`s in scope, the name "node" is ambiguous.

Take into account that not all libraries are grouped into packages
avoid collapsing such libraries into the root node.

We already make the callsites use dyn:* selectors for normal method
calls as well as setters, this is doing the same thing for getters.
Once callsites use dyn:get:* various pieces in runtime need to be
adjusted to accomodate for that (e.g. NSM handling, etc).
A follow-up CL will then start actually generating dyn:* getters in
certain situations.

This CL adds --trace-precompiler-to option which generates a machine readable
precompiler trace (list of all compiled functions and their dependencies).
It also expands package:vm_snapshot_analysis with tools for reading and
analysing this trace.
For example snapshot_analysis explain dynamic-calls command allows
to list all dynamic calls sorted by their impact on the size of the AOT
snapshot.
