Regis Crelier 7f57ebcfa1 Remove signature classes from the VM.
They were used as the class of closure instances and as the type class of
function types.
All closure instances now have class _Closure and function types are represented
by a new class FunctionType extending AbstractType.
Fix issue 24567 and add regression test.

Ryan Macnak 6b964b83ac Add ./tools/test.py -c precompiler -r dart_precompiled.
- Make --gen/run-precompiled-snapshot take a directory to use for the snapshot pieces.
 - Throw on Platform.executeable to prevent tests from becoming fork-bombs.
 - Update status files so 'dart_precompiled' is generally expected to behave the same as 'vm'.

Currently multitests will fail unless run with --jobs=1 because the test harness assigns them the same temporary directory.

Running this also requires a great deal of space. My out directory is 380G.

John McCutchan da946fbf99 Simplify timeline backend
Now that we have a central list of all threads that are interacting with the VM we can stop relying on the Isolate's thread registry to cache timeline blocks.

- Move from caching blocks in the Isolate's thread registry and caching them in the Thread directly.
- This allows cached blocks to have events from multiple isolates, increasing usage density and reducing the number of blocks being cached at any given time.
- We no longer need a distinct global block, this allows me to remove a bunch of dead code.

Todd Turnidge 0d501ad53d VM restart + shutdown fixes
This change add the ability to restart the vm through the service
protocol.  All isolates are killed, and then the main isolate is
restarted cooperatively by the embedder.

This change also fixes the message handler to prevent it from
accidentally ignoring vm shutdown messages.

Previously, we would stop handling messages whenever we hit an error
(such as a compile error or an unhandled exception).  This would leave
shutdown requests sitting the oob queue, neglected.

We now process *all* oob requests, up to the first shutdown request.
When we hit a shutdown request, we clear the oob queue and process no
more messages.

To make all of this work, we had to change the return value of
HandleMessage from bool to a new enum type, allowing the message
handler to distinguish *normal* error cases from the more rarified
shutdown and restart cases.
