This also ensures that a launcher that fails after being closed doesn't
break anything.

Rather than trying to keep up with the latest and greatest
implementations of Function.toString, this just avoids verifying the
function string values at all.

This captures some syntax errors that were previously falling by the wayside,
and cleans up some edge cases in displaying syntax errors in general.

This reduces a bit of the duplication between the compact and expanded
reporters, and sets the stage for better loading in the future.

Add support for checked mode

Platform.executable doesn't include the ".exe" extension on Windows,
which causes symlink resolution for it to fail.

It turns out this was already happening, since "pub run" defaults to
checked mode for all non-global executables. However, this won't always
be the case; see dart-lang/pub#1230.

Closes #130

Since we don't load isolates from code being generated by the main
isolate, there's no need to work around dart-lang/sdk#12617. This
dramatically decreases load times for VM tests.

Fix a bunch of broken tests.

Closes #120

Convert most Future-based code to async/await

Now that we only support Dart >=1.9, all supported Dart versions support
Isolate.kill().

Now that we use async/await, we're no longer compatible with Dart 1.8.

This moves the logic of starting the server and extracting its port
number to a utility function.

This makes it much easier to implement asynchronous methods and memoize
them or make them reentrant.

Convert JS stack traces into Dart stack traces.

Don't wait for every suite to load at once—this basically ensures that
once there are enough, later ones will time out. Instead, only load

stack_trace 1.2.0 isn't compatible with test.

I tried `pub downgrade` and I got the error

 `Class 'LazyTrace' has no instance method 'foldFrames' with matching arguments.`

 After limiting stack_trace to '^1.2.1' it worked again.
