- Forward only kImportTag requests to DFE. This restores the current handling of a kScriptTag request when loading the kernel isolate in the simulators.
- Mark dynamic_load_test as failing in the reload stress tests (reload fails to preserve library identity).

Kernel mixin transformation desugars mixin applications into normal
classes. Mixed-in type is pulled into interfaces list.
However, dart:mirrors needs to know the original mixed-in type of
a mixin application.
This change solves this problem by propagating a 'isTransformedMixinApplication'
attribute of a class through kernel AST, kernel binary and VM objects
into dart:mirrors implementation.

Add function_type_arguments field in closure instances.
Lots of other smaller changes, also related to generic function semantics.
This is still work in progress, with a change of direction in the design:
The type argument vector of a generic function will be prepended with the type
arguments of enclosing generic functions. The re-allocation and concatenation
will be done in nested generic function's prolog. This will greatly simplify
instantiation of types at run time without having to search the context for
parent function's type arguments. However, a closure instance now requires an
additional field. On the other hand, type parameters do not require a
parent_level field anymore.

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.

type itself gets instantiated.
Until now, the signature was kept unchanged and the instantiation was reflected
by the type arguments of the function type only. This delayed instantiation
would complicate the implementation of generic functions.
This cl actually removes type arguments for (non-typedef) function types. The
function type is now fully represented by the signature. When the function type
is instantiated, a new signature is allocated (instead of a new type argument
vector) to hold instantiated result type and formal parameter types.
The same applies in the case of typedef function types, however, the type
arguments of the typedef are kept as before. This allows for better printing
of typedef function types and for finalization of recursive type involving
typedefs as type arguments.

Add regression test and mark as failing for the analyzer (issue filed).
Add missing trail argument in 2 locations (not related to the fixed issue).
Cleanup: Remove ClassFinalizer::kCanonicalizeWellFormed which is not treated
differently than ClassFinalizer::kCanonicalize anymore after earlier changes in
the spec on how to handle malformed types.

Simplify handling of closures as deferred objects.
The name "type_arguments_" is confusing, because class Closure is not generic.
Class Closure was forcefully made (kinda) generic by setting its
type_arguments_field_offset_in_words_ field to a valid value, so that the
type_arguments_ field in closure instances could be accessed similarly as in
generic instances. With generic functions, closures will potentially have more
than one instantiator and the name type_arguments_ becomes nonsensical.

The CL adds metadata support for Fields/Classes/Functions/Constructors. There
are other places where annotations can be put in the Dart language but the
Kernel IR currently does not store it in the AST.
Whenever a element (e.g. a function) gets annotated, the VM will make a [Field] for this
element whos value is an array of evaluated constant metadata annotations.
This CL attaches to these [Fields] a `kernel_function` which is then used to do the constant
evaluation.

This was a pull request: 8a8033a417
MirrorsUsed doesn't transitively include reflective information. However, it must still be able to create TypeMirrors for types that are used as return- or parameter types.
Initially, the patch checked that TypeMirrors had the correct number of arguments for generic types. This is now disabled.
A better approach would be to know if a class has full reflective information, or not. But this would require much bigger changes to the system.

* Basic implementation of reflecting generic types using dynamic list of type arguments
* Removed redundant expectation in test
* Added basic support for dynamic type arguments in reflectType of js_mirrors
* Fixes according to code review comments: major cleanup, added more test cases and updated docs
* Updated JS mirrors reflectType() to match behavior of VM implementation
* Terminate exception messages with a dot; Improved error handling for empty argument list and type checks;
* Use NumTypeParameters when checking provided argument list size
* Check if type arguments are malbounded; added test cases for typedefs and mixins
* Uncommented a test case
* Updated lib.status to mark some tests as failing in dart2js due to limitations in JS mirrors
* Fixed mixin test mock definition; updated configuration for tests requiring checked mode
* Handle nested generic types in type argument parsing (JS)
The analyzer has a stricter patch parser than the VM. Patch files
cannot change signatures of patched members. Specifically, they cannot
change:
- the return type
- a parameter's name
- a parameter to an initializing formal
- an optional parameter's default value
