zerny@google.com 94a510176b Copy irregexp related code from V8. 
This "syntactic" change copies the irregexp code from V8 r24065 to Dart.
Compared to the V8 files the only changes are that the files have been
suitably renamed, headers and footers have been updated, and most of the
unneeded code has been replaced by a 'SNIP' marker. None of the files
are added to the build and they cannot compile. Integration with the
Dart VM is done in a follow-up CL [1].

fschneider@google.com 876193b31a Make CTX allocatable by the register allocator. 
This change makes CTX available by not caching the current
context while in Dart code. Instead the current context
is held in a local variable (:saved_current_context_var) and
is passed as argument in CTX at calls.

This also simplifies a lot of code in the debugger: As a result,
Isolate::top_context is not needed anymore since the current context
can always be extracted from a Dart frame.

Allocates hidden extra memory after VirtualMemory, and
verified writes are duplicated at a fixed offset.

This CL only adds the helper.
Next steps:
1. Use Reserve when reserving semi-spaces and heap pages.
2. Use Write for storing pointers (+ offset in generated code).
3. Use Accept for GC-related object lifecycle.
4. Call Verify regularly.
5. Fix failures (= places where we forget/ignore write barriers).

zra@google.com 306ef8dd75 Fixes leak in Process.runSync(). 
This removes the call to _stdin._sink.destroy()
from my previous CL, which broke a test.
stdin is closed by the native implementation.
Closing again shouldn't cause a problem, but
it looks like destroy() attempts to do a lot
more than that.

OTOH adding the remove call is sufficient to
fix the leak, so let's just stick with that.

turnidge@google.com c658fa60f9 Fix deadlock that can occur while handling service messages at a breakpoint. 
Deadlock looks like:

  Regular Isolate
  -> paused at breakpoint in debug message loop
  -> holds debug message queue lock to get message notifications
  -> handles an service message
  -> waits for portmap lock to send response

  Service Isolate
  -> receives request for paused isolate
  -> holds portmap lock to send message
  -> runs custom message notifier to wake debug message loop
  -> waits for debug message queue lock

I've solved this by releasing the debug message queue lock while
handling service messages.  This requires me to poll for new service
messages after reacquiring the debug message queue lock to make sure I
haven't dropped any notifications.

It's a little weird that the embedder (runtime/bin) needs to be aware
of the locking in the core vm (runtime/vm), but this seemed like the
simplest fix for now.

fschneider@google.com 1dc4e979d9 Remove isolate pointer from context objects. 
By moving all stubs that do runtime calls into the isolate
we don't need to cache the current isolate in each context
object.

This saves space on each context at the cost of duplicating stubs
in each isolate. Most stubs are already isolate-specific and the total number
 of stubs is small enough for this to be a good trade-off.

kustermann@google.com 360dfe4f41 Several bugfixes in dart:io's handing of sockets 
This CL includes fixes for the following issues:

a) The event handler created listening socket metadata (values of a hashtable
indexed by filedescriptor) sometimes as SocketData and sometimes as
ListeningSocketData depending whether the socket has been listened to or not.
This was very buggy, in particular because multiple isolates can have a
reference to the same server socket in different states (opened, listened,
closed).

=> This should be fixed by sending the file descriptior typeMask always to the
   eventhandler.

b) A server socket cloned via the ServerSocketReference mechanism, opens a
receive port for sending (fd, address, port) to isolates/... which want to
create a server socket from the reference.
This receive port was not closed properly when calling only close() (and not
listening first).

=> This should be fixed by closing this receiveport on the ServerSocket.close()
   call as well.

c) It was assumed in the event handler that a close command needs to have the
Dart_Port in a hash table. But this is only the case if the user actually
listened to the ServerSocket. Otherwise the event handler does not know about
the server socket. This caused a NULL dereference which resulted in a SEGFAULT.

=> This should be fixed by checking if the Dart_Port is in the hashmap of the
ListeningSocketData or not.

d) Too many bits were considered when extracting token count in C++ code.

The CL includes a regression test which should trigger these issues.

koda@google.com 516a33a0cc Avoid races in capacity accounting. 
Use pages_lock_ to sync access to usage_.capacity_in_words.
Also remove ASSERT no longer valid with concurrent sweep.

This does not resolve the more general issue of the growth policy not being perpared for concurrent sweeping.
