d55d3ce89a Add DebugMessageDispatchHandler 
A callback on the debugger thread when a message is received. Allows the 
embedding application to wake up the main thread in order to handle the 
message. Useful when the embedding application is idle and sitting in a 
select() call.

9a545949a4 Restore invariant (next of first deallocated must point to the head) before calling into weak 
callbacks.

Otherwise if callback allocates a new handle, it could orphan some global handles (with disastorous
consequences if those global handles are cached).

53bee811ad Re-enable using push instructions for syncing the virtual frame. 
This change fixes the problem with the original version of this approach
(r3032) that may lead to a corrupted stack if we would invoke spilling during 
syncing a large SMI constant (unsafe SMIs) in the virtual frame.

The new code for storing unsafe SMI constants does not use an extra temporary 
register. This prevents the compiler from ever having to spill during a 
virutal frame sync operation.

For storing a large SMI constant we previously generated:

  mov ecx, (large_smi & 0x0000ffff)
  xor ecx, (large_smi & 0xffff0000)
  push ecx

we now generate:

  push (large_smi & 0x0000ffff)
  or   [esp], (large_smi & 0xffff0000)

Not using a temporary register avoids spilling within an nvocation 
of VirtualFrame::SyncRange.

9bafc32932 Step next should respect do/while condition block. 
Condition block of do/while statements is a valid break location so it should have its own position. The block is represented by a regular Expression node so we cannot store the position in it, instead the position is stored in a separate field in DoWhileStatement AST node.

5820f951c1 Improve the allocation and initialization of locals on IA32 in the top-level compiler. 
This optimization is already done on x64 and ARM. 

Until now we used a push immediate for each local variable on IA32:

  push $undefined
  push $undefined
  ...

to initialize each local variable. This change does:

  mov eax, $undefined
  push eax
  push eax
  ...

they activated Snapshot::enable() too late after code had been
generated that assumed no snapshots.

1560b89888 Top-level compiler: Re-allow non-lazily compiled function literals. 
This change re-allows non-lazy compiled function literals for top-level compilation.

There was a problem on ARM exposed through this change which was fixed as part of r3289
in fast-codegen-arm.cc (Threading and Threading2 tests failed)

It occurred before r3289 when we allocate a local context at the beginning of a function. The
code for the stack check was split up in an unintended way (load of stack check limit into r2, 
and use of r2 in the actual stack check code).

963d72ff57 Revert r3032 that uses push instead of 'sub esp, size'. This change 
leads to stack corruption in 32-bit version of V8.

See http://code.google.com/p/chromium/issues/detail?id=27227 for a
reproducible case.

Since this is only an issue on 32-bit V8 I think this has got
something to do with the UnsafeSmi handling that we do on ia32.  I'm
reverting for now so we can push a fix, but we should track down the
issue and create a regression test for this.

91cc4c7ebb Modify test using string slices 
With slices string string type removed generating a large amount of sub-strings takes more time. Change a test to avoid timeout in debug mode.

851b9b2f73 Remove sliced string string type 
As a first step to reduce the complexity of the string hierachy the sliced string type is removed. Whenever a sub-string is created it is allocated as a fresh flat string.
