Make the compact linked hash map, which is the default implementation for Map (including map literals), a VM-internal class. This makes it easy to have more efficient serialization of maps (although for now, the implementation is straight-forward). Refactor the compact hash class hierarchy to enable the VM-internal class and the rest (also the Set classes) to share a maximal amount of code, by using two different bases for implicit/explicit fields. Remove existing proof-of-concept, C++-based internal VM-class. BUG=http://dartbug.com/22982 R=asiva@google.com Review URL: https://codereview.chromium.org//1151523002
