Vyacheslav Egorov 2fed1c3905 Merge more Kernel infrastructure from kernel_sdk SDK fork. 
- bring patched SDK generation scripts and VM patch tweaks that allow VM patch files to be parsed by analyzer front-end;
  Patched SDK is an SDK with all VM patches spliced into it. Kernel compiler is based on the analyzer front-end which does
  not have any patch files support/model so for it to produce Kernel files that match VM we need to generate a such patched SDKs.

- bring test script modifications that allow to test Kernel pipeline

Vyacheslav Egorov f4ec20abac Recognize and optimize a.runtimeType == b.runtimeType pattern. 
Start by removing all get:runtimeType overrides in the patch files to have a single point computing the runtime type - Object.get:runtimeType. Handle string, double and integer types inside both intrinsic and runtime call to unify their handling and guarantee that code works even with intrinsifier disabled.

With overrides removed we can easily check that get:runtimeType is unique function name within the application that is being precompiled and use that to convert InstanceCall(get:runtimeType, ...) into StaticCall even nothing is known about the receiver.

This enables us to check if both left side and right side of comparison are StaticCall(Object.get:runtimeType, ...) when specializing InstanceCall(==, x, y). If they are we convert InstanceCall(==, StaticCall(get:runtimeType, a), StaticCall(get:runtimeType, b)) into StaticCall(Object._hasSameRuntimeType, a, b). A canonicalization rule will later delete unused get:runtimeType invocations.

Object._hasSameRuntimeType is implemented in C++ and intrinsified. It operates without creating new runtime types (except for Closures - where it does for simplicity). Cases of different class ids (i.e. a.[cid] != b.[cid]) and non-parameterized types are handled completely in the intrinsic. The rest is handled in the runtime code.

Microbenchmarking results:

Same parameterized classes: 15x improvement
Different parameterized classes: 300x improvement
Different/same non-parameterized classes: 2x improvement

Matthias Hausner 1a6d1eca32 Implement @patch annotation for patch class members 
Allow members of patch classes to be annotated with @patch. The VM
ignores the annotation. I simply replaces the original method
if the name matches, or reports an error if field names match.

Adding a bit is_patched to members to do more checking remains a
TODO. There are currently no unused bits available, and I don’t want
to increase the size of Function objects for this.

Matthias Hausner e11ca24053 Use metadata annotation @patch for patch classes 
Annotate patch classes and top-level patch functions with @patch
instead of the pseudo-keyword patch. This allows the analyzer
to read patch files, and matches the syntax that dart2js uses.

The deprecated syntax is still supported, but a warning is printed when detected.

fschneider@google.com 9031c80c88 Change == into an instance call to allow polymorphic inlining of ==. 
In unoptimized code equality is now just another instance call.

The optimizer replaces it with a specialized implementation based on static
 type information and type feedback.

Many of the manual optimizations of == in the optimizer are now just handled
 by the generic inliner, plus polymorphic inlining of == calls is now possible.
This also eliminates the need for a lot of duplicated code in the backend.

I adapted the inlining heuristics to compensate for the slightly larger
inital flow graph size.

This leads to error message issues in dart2js which I have patched up
the best way I could find.
