Stephen Adams 101a83f2f4 dart2js: Reduce overhead of --verbose measurements 
ZoneSpecification and zoneValues are now per-task, rather than per measurement.
This reduces total LinkedHashMap allocations by 30%

In the large compile I am using to measure these things, there are still
~3M zones created via Zone.fork and 10M _ZoneFunction objects allocated, and the Zone.fork copies the (now cached) LinkedHashMap.
So cross-task measurements are still quite expensive.

Johnni Winther e6241bc12d Include constants in deferred computation. 
This ensures that in-code constants are included in the deferred computation.

Currently the set of live constants is not computed in itself, so the constants
used in the computation are not the same - and they are generally larger than needed.

Stephen Adams 478106bce2 dart2js inferrer: don't infer widened type when unreachable 
'&' and '|' were missing the case to return 'empty' if the argument was empty, causing the widened (default) type to be propagated.

There are a few bitwise operations in the streams code that have better code from being slightly more precise.

Stephen Adams 9d5fd9d5bd Avoid using call-through stub on calls to fields. 
This usually removes the demand for the call-through stub and sometimes enables optimizations on the field load, e.g.:

    WhereIterator: {
      "^": "Iterator;_iterator,_f",
      moveNext$0: function() {
        for (var t1 = this._iterator; t1.moveNext$0();)
          if (this._f$1(t1.get$current()) === true)
            return true;
        return false;
      },
      _f$1: function(arg0) {
        return this._f.call$1(arg0);
      }
      ...
-->
    WhereIterator: {
      "^": "Iterator;_iterator,_f",
      moveNext$0: function() {
        var t1, t2;
        for (t1 = this._iterator, t2 = this._f; t1.moveNext$0();)
          if (t2.call$1(t1.get$current()) === true)
            return true;
        return false;
      },

Stephen Adams 5923966da3 Feature-detect browser for assignment to __proto__. 
Assigning to __proto__ is a fast way to stitch together a number of
object literals into a prototype chain without copying all the
properties.

Unfortunately this leads to very slow execution on Firefox (and
jsshell).  So now we feature-detect Chrome (and d8) since that is the
only browser we know currently can use the 'fast' startup path without
penalizing subsequent performance.

This speeds up some jsshell benchmarks by 30%.

Erik Ernst 6942e0df63 Fixes bug in scoping for generic methods. 
The updates to tests/language/generic_local_functions_test.dart use a
local function type argument in its return type, which had not been
tested and did not work.

After a bunch of attempts to change the order in which the resolution
is performed, it suddenly turned out that the offending statement
`visit(node.returnType)` in `ResolverVisitor.visitFunctionExpression`
might be redundant! (.. a subsequent re-resolution in
`ResolverVisitor.analyze` performs the same job, and uses the correct
scope).

So this CL simply removes that `visit..` statement, and the resulting
`dart2js` passes all tests.

Johnni Winther 1f1e00f012 Handle redirects to unresolved redirects 
The solves the handling of redirecting factories that redirects to other
redirecting factories whos immediate redirection target is unresolved.

For instance

  class C {
    factory C.a() = C.b;
    factory C.b() = Unresolved;
  }

The implementation normalizes the properties 'immediateRedirectionTarget',
'redirectionDeferredPrefix', 'effectiveTarget', 'effectiveTargetType', and
'isEffectiveTargetMalformed' by always storing the information on the
implementation element.
