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 Issue https://github.com/dart-lang/sdk/issues/31709 Change-Id: I0a73ad620e051dd49c9db7da3241212b3b74ccdd Reviewed-on: https://dart-review.googlesource.com/c/92740 Commit-Queue: Martin Kustermann <kustermann@google.com> Reviewed-by: Aart Bik <ajcbik@google.com>
