With generic methods, uninstantiated types will require 2 instantiators, one
reflecting the class type arguments (as of today) and one reflecting the
function type arguments (new).
This is work in progress and the second instantiator is always null for now.

This reverts commit d44fec08b0.
Remove special-cases for known types (int, String, num, double, Smi). The generic
lowering into an instance call (_simpleInstanceOf) works just fine for these predefined
types.
Also, remove parameter for negated is-tests. Instead insert explicit negation when.
building the flow graph.
Diff to original CL:
* Correct number of arguments in invocation of _instanceOf in kernel_to_il.cc.

The function _fatal is only used in dart:async. Change it from a public
function of dart:_internal, which can be invoked via mirrors, into a
private function of dart:async.

_fatal was a private function in dart:core which was called from a
different library (dart:async). It's not clear how it was supposed to
work or if it even did. The uses in dart:async don't appear to be
covered by tests.
Move it to dart:_internal which exists exactly for sharing things
between the dart: libraries.

This reverts commit 890f694de5.
Previous commit was passing field_type_map_ down in a place where it was not passed down before.
This caused some handles to be used across zones, which caused crashes.

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

- Use TokenDescriptor instead of intptr_t for all token positions.
- Use TokenDescriptor in raw_object instead of int32_t.
- TokenDescriptor is a POD with an int32_t (this shrinks the size of AST and IR nodes by 32-bits on 64-bit architectures).
There are some cleanups I plan on doing as a follow up CL:
- Replace TokenDescriptor::value() with TokenDescriptor::TokenPos()

They were used as the class of closure instances and as the type class of
function types.
All closure instances now have class _Closure and function types are represented
by a new class FunctionType extending AbstractType.
Fix issue 24567 and add regression test.

- Complete revamp of isolate-specific flags.
- Associate flags with the isolate on creation.
- Dart_CreateIsolate and associate callback do take an
extra flags argument.
- Make sure to clear IC data array when clearing code.

First step towards deferred library support:
- Parse the “deferred as” import clause.
- Implement p.loadLibrary() which returns a future that
completes when the library is loaded.
- Treat type annotations of deferred types as malformed.
- Throw NoSuchMethodError when calling functions from
unloaded libraries.
- Libraries are still read synchronously, but items in the
library won’t be visible through the deferred prefix until
the future returned by loadLibrary() completes.

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.
