This CL adds a new target for kernel front-end, vm_precompiler. This is
an experimental target for new Dart VM precompiler pipeline which
will fully exploit strong mode type system and perform whole-program
optimizations.
As an example of such whole-program optimization, this CL adds
draft implementation of devirtualization of method invocations, which
uses single target computed by closed-world class hierarchy analysis.
Corresponding null checks (required for correctness) are not generated
yet.
