This also moves some common code from jit_optimizer.cc and aot_optimizer.cc to
a new common file, optimizer.cc. The code is almost unchanged from the
aot_optimizer.cc version, apart from the calls to PurgeNegativeTestCidsEntries.
A flag emulates the behaviour of the simpler jit_optimizer.cc version.
Benchmark tests are running to see which is better.

- Separate out parsing a status file from applying the environment to
determine which sections are active. This makes it possible to, for
example, generate expectation sets for multiple environments without
having to reparse each time.
- Simplify expression parsing. Remove set expressions since they weren't
used for anything useful. A test's expectations are a simple
comma-separated list and don't need anything beyond that. Merge
Scanner and Tokenizer since the latter was a glorified function.
- Make more names private so that it's clearer what's used outside of
various libraries.
- Generally modernize the style.
- Add *lots* of documentation.
Again, there should be no behavioral changes. I ran:
./tools/test.py -m release,debug -c none,dart2js,dart2analyzer -r none,vm,d8 corelib
Before and after the change and verified that the output was the same
(aside from timing).

The current old-space allocation implementation performs a
linear search in a single (potentially *very long*) free list for
allocations > 2k.
This CL will change this behavior to limit the number of free list
entries traversed, falling back to allocate a new page if the maximum
number of steps was reached. The new page will be pushed onto the
front of the free list, therefore making new allocations go there
immediately.
For the new tests/standalone/fragmentation_test.dart we
- pay around 11-12% increase in memory
- to gain a 6x speedup (125x speedup with sweepers disabled)
I tried a much more complicated version that had power-of-two
buckets for freelist items > 2k. This turned out to regress
dart2js and splay for reasons that I could not determine. This
version is much simpler and fixes the issue as observed in the
bug.

There are far too many files here to review everyone carefully.
Spot checking most of the diffs look good as test code is generally written
with less care than application code so lots of ugly formatting get through.
If people notice files where the automated formatting bothers them feel free
to comment indicating file names and I'll move spaces within comments to make
the formatting cleaner and use comments to force block formatting as I have
done for other case where formatting looked bad.

If an Isolate touches the 'stdio' getter, a _NativeSocket with
attached finalizer is created for it. Previously, when such an
Isolate exited, the finalizer would close the underlying
file descriptor. This CL changes the finalizer for stdin such
that the native objects will be cleaned up, but the underlying
file descriptor will not be closed. The underlying file
descriptor will now only be closed if the stdin stream
subscription is explicitly canceled.
Accessing the stdin getter after the stream is explicitly
canceled will result in a FileSystemException.

The finalizer sends the "close" message to the EventHandler for the
file descriptor in the _NativeSocket's native field. To avoid races and
spurious messages, this CL stores a pointer to a wrapper object in the
native field instead of the file descriptor. All messsages about the
_NativeSocket sent to the EventHandler use the wrapper object instead of
the file descriptor. When the EventHandler closes the file, the file
descriptor in the wrapper object is set to -1 so that the finalizer will
instead do nothing.
On Windows, there is another level of indirection since the OS HANDLEs
were already wrapped in various kinds of Handle objects. As an additional
complication, ClientSocket close on Windows is asynchronous, so the
EventHandler may shutdown before all of the ClientSocket Handles can be
destroyed.

For now both old and new styles are allowed to accommodate CO19 tests.
