Martin Kustermann 525b43d747 [vm] Decouple intrinsifier code from runtime
This is the next step towards preventing compiler from directly peeking
into runtime and instead interact with runtime through a well defined
surface.

This CL decouples the hand-written intrinsifier code from the runtime:

  * the intrinsifier is split up into a GraphIntrinsifier and AsmIntrinsifier
  * the recognized methods list is moved to a separate .h file
  * all intrinsifier code is moved into dart::compiler namespace
  * the AsmIntrinsifier is only interacting with RT through runtime_api.h
