058deb2713 Debugger: use list to find shared function info in a script. 
Now that we keep tabs on shared function infos from a script, we can speed up finding shared function infos for debugging. However, in case we have to compile a function that cannot be lazily compiled without context, we fall back to the slow heap iteration.

af4c4b0427 Reland 'Additional HandleScopes to limit Handle consumption.' 
v8 builds with --no-snap were hitting handle limits compiling natives for handle count unit tests that run with --check_handle_count. Patch now has higher handle limits (~4k more than required for failing natives compilation).

agcloud.js from 80,738 to 8,176.
    >
    > No significant handle count issues found with major websites, but substantial savings on some benchmarks and demos:

cf21d22fd8 Serializer: commit new internalized strings after deserialization. 
Reserving space for deserialization can cause GC, which
can evict entries from the string table. Having more deleted
entries now, StringTable::EnsureCapacity could cause a GC
later during deserialization even when we actually still
have enough capacity.

Instead, we now keep new internalized strings in a separate list
and commit them to the string table at the end.

28b0129b03 Fix cluster-fuzz regression when getting message from Worker 
The issue is that Worker.prototype.terminate was deleting the C++ Worker
object, and then Worker.prototype.getMessage was trying to read messages from
the queue.

The simplest solution is to keep workers in a zombie state when they have been
terminated. They won't be reaped until Shell::CleanupWorkers is called.

I've also fixed some threading issues with Workers:

* Workers can be created by another Worker, so the Shell::workers_ variable
must be protected by a mutex.

* An individual Worker can typically only be accessed by the isolate that
created it, but the main thread can always terminate it, so the Worker::state_
must be accessed in a thread-safe way.

afb3119915 PPC: Vector ICs: Like megamorphic keyed koads, use a dummy vector for stores 
Port 9e7af9efc5

Original commit message:
It's useful for the megamorphic keyed store case to not require a
vector and slot as input. Analogous to the load case, we have a dummy
one-ic-slot vector to aid. Since the only kind of MISS is for
megamorphic cache stub failures, we don't need the real vector.
The reason is that megamorphic cache stub failures don't result in any
change to the type feedback vector state.

cfe89a71a3 Debugger: use list to find shared function info in a script. 
Now that we keep tabs on shared function infos from a script, we can speed up finding shared function infos for debugging. However, in case we have to compile a function that cannot be lazily compiled without context, we fall back to the slow heap iteration.

1d73a81ae0 Remove obsolete options in ScriptCompiler::CompileOptions. 
This is a follow-on to https://code.google.com/p/v8/source/detail?r=22431
This will remove the compatibility logic, so that the API as described
in r22431 is the only API.

I'll let this CL will sit around for a while to give embedders a chance
to update their code.
