Sigmund Cherem d9c6bc0316 Improvements to verbose timing data printing. 
- format is padded and includes  %
- measure explicitly subtasks of deferred load
- use shorter names for other tasks

Stephen Adams 849ece596a [dart2js] Use properties on Closure class for one common case 
We can share the properties for single-argument closures by putting
the properties on class Closure. (It is worthwhile to do this for zero
and two argument closures, but we will need to add subclasses. That
will be another CL).

Johnni Winther a9e2af657f Refactor static type computation 
This decouples the computation of static types from the kernel impact
visitor and prepares for flow sensitive static types (i.e. guarded type
promotion).

Stephen Adams 36874154b4 [dart2js] Simplify defaulting bool. 
The small diamond from `boolOrNull ?? false` can become a fast comparison:

    boolOrNull == null ? false : boolOrNull  -->  boolOrNull == true

The straight-line code is then available for other optimizations, e.g. generate-at-use placement.

Sigmund Cherem 61df5fdec8 Encode dart2js source-map extensions in strings. 
This reduce the memory footprint and cost of parsing these extensions.  Another
advantage is a reduction on the size of the .map files.  On a large customer
app, this was a 11% reduction, and the frames section was about 1Mb (excluding
the extra names and uris added on the existing tables).

The encoding works as follows:
 - minified names are written as a list of names and indices, in pairs.

    {'n1': 1, 'n2': 2} => 'n1,1,n2,2'

 - frames are encoded using a sequence of values with markers for the different
   kind of frames. Numbers are encoded using VLQ deltas. We use VLQ because it's
   already available to any parser that deals with the mappings).

This change also uses the dart2js_tools parser implementation for all unit tests.
