Function type parameters in occurring in constants were using an offset
based on the context in which the constant first occurred. This meant
that function type parameters occurring in a generic context would have
a different offset that those occurring in a non-generic context.
The loading of .dill in ast_from_binary would read all constants outside
the context and would therefore get the indices wrong on generic
function types.
This CL changes the encoding of these type parameters to always use
a fresh context.
Closes#45415

The web compilers don't support getter/field invocation encoded as a
FunctionInvocation on an InstanceGet because it doesn't work for
getter/field invocation of js-interop properties, since the InstanceGet
wouldn't result in a Dart function but just JavaScript function.
To support this in the new method invocation encoding, a special
expression, InstanceGetterInvocation, is used to encode getter/field
invocations in dart2js and ddc.

The CL is a step towards have a more restricted and wellstructured
handled of references and canonical names.
The CL moves Reference to canonical_name.dart and makes
CanonicalName.reference private, and replaces CanonicalName.getReference
with a 'reference' getter.
It also removes NamedNode.canonicalName, Field.getterCanonicalName and
Field.setterCanonicalName so that these can only be accessed through the
corresponding reference. This is to reduce the reliance on the
canonical names which, ideally, should only be part of serialization and
deserialization.

The front end previously enforced a stricter-than-spec requirement on
conflicting imports on its own code. The check was included of the
kernel snapshot and therefore always enforced, even in published sdks.
The extra check was removed a month ago and now tools/sdks/ have been
updated to use a later version of the sdk, so the unneeded hide
combinators can now be removed from the source code.

This CL adds stub for each concrete mixed in member into mixin
applications. The body of the stub calls the original member via
a super call.
This addition means that resolution of super access now use the
stub and not the original declaration as the target, which means
that it will be correct even when mixed in members are cloned. For
this reason, dart2js no longer needs to perform its own super
member resolution.
When a super call targets a mixin super stub (after cloning) it
can be optimized away by redirecting the call to the `stubTarget`
of the call. This optimization is performed in dart2js.
Since dart2js now uses the correct super target, its runtime
mixin application needs to avoid overriding members already
declared in the mixin application. These members are the
forwarding super stubs which ensure that correct runtime types
when members with covariant parameters are implemented.
