Johnni Winther b0ecbef3cc Introduce isAbstractlyInstantiated to avoid exact masks of abstract classes. 
Classes can be instantiated directly, abstractly or indirectly:

When [cls] is directly instantiated: This means that at runtime instances of exactly [cls] are assumed to exist.

When [cls] is abstractly instantiated: This means that at runtime instances of [cls] or unknown subclasses of [cls] are assumed to exist.

This is used to mark native and/or reflectable classes as instantiated. For native classes we do not know the exact class that instantiates [cls] so [cls] here represents the root of the subclasses. For reflectable classes we need event abstract classes to be 'live' even though they cannot themselves be instantiated.

When [cls] is indirectly instantiated: This means that a subclass of [cls] is directly or abstractly instantiated.

Stephen Adams 7eaad70e2f Improve condition strengthening for last test in short-circuit. 
This strengthens

   t1 = s == null || t == null;
   if (t1) return;
   known-here:  t != null

There are not many hits since the 'interesting' tests are usually
earlier in the short-circuit expression.

Stephen Adams 3b5c154138 Don't gvn HForeignCode without source text 
There are a few synthetic templates that are generated from trees instead of source text. I don't think any are marked for GVN, but this is a hazard so best fix it.

Johnni Winther 37afcd5197 Change TypeInference to handle super calls as direct invocations. 
This also makes calls of known target registered as static uses and thus

Erik Ernst b5d2b38aa3 Relaxes treatment of method type parameter in as expressions. 
This CL changes the semantics of `dart2js --generic-method-syntax`
generated code for `e as T` where `T` is a method type parameter.

The old behavior was to raise a `TypeError` at runtime when such an
expression was evaluated. The new behavior is to consider `T` as an
alias for `dynamic`, i.e., `e as T` will then always succeed.

Addresses part of issue 27460, omits a part that is not yet agreed upon.
