d98baf8098 Fix DevTools CPU profiler after isolates merge. 
There was an obvious bug with missing call to SamplerRegistry::GetState.
I've also updated CpuProfiler to avoid stopping sampler, if it didn't started it.

04537cb227 Use v8::internal threading support in samples/shell.cc. 
We need this for isolates testing. To make it work I had to extend the
internal Thread constructor with an option to set the stack size (see
the comment in shell.cc).

4bb55fd341 Change cctests to use variant flags as part of the name for the serilization file. 
Because we run all tests three times with different variant flags (to
test crankshaft) we might end up in a situation where we try to write
to the same serilization file from two different threads
simultaneously. The patch concats the variant flags at the end of the
serialization file name.

8066271fd2 Optimize calls to object literal properties that are initialized with a function literal. 
This allows fast calls and inlining of functions like:

var o = {f: function() { return "foo"; }}
o.f();


Object literals that contain function literals are initially created a dictionary mode
object and only transformed to fast properties once all properties are computed and
added. This allows us to create constant function properties for functions declared
inside the object literal. Function literals inside object literals are marked for
pretenuring so that they work as contant function properties.

Object literals without functions should just function as before.

e820926108 Improve ARM-Simulator. 
This patch
- removes the unimplemented code crash when rendering invalid/unknown instructions and prints "unknown" instead.
- prints the beginning of the constant pool marker.
- adds "da" as a shortcut for "disasm".
- print hexadecimal representation of double and single registers. This makes it easier to debug move/conversion code that uses temporary int32 values in floating point registers.
- annotates the stack with short prints of the values (HeapObjects and smis),
- makes disasm take an address or a register as second argument without a third argument, which defaults to printing ten instructions.

c6e37c5dfb Make Script.prototype.nameOrSourceURL use indexOf search first before trying to match with a RegExp. 
This should use Boyer-Moore search with a long string, which is potentially
faster than RegExp search.
The target string is typically, but not guaranteed, at the end of the
source, so for long sources, there will be a lot of characters to skip.

4722f692e4 Make exception thrown via v8 public API propagate to v8::TryCatch as JS thrown exceptions do. 
Correctly process failures which can be returned by Object::GetProperty
when performing GetRealNamedProperty* queries.

Callback properties can produce exceptions so we need to wrap access to them
into exception checks.  However, despite of many other methods with exception
checks, property access doesn't mandatroy go via JavaScript and hence we
need to inject code to propagate exception to public API TryCatch handlers.

351a108dfc ARM: Fix the debugger using wrong break stub for slot breaks 
On ARM the break at break slots wrongly used the break at return stub which assumes an object opinter in r0. At break slots there are no objects live in registers so a GC while at a break on a break stub could cause a crash as r0 was wrongly pushed on a internal frame to be handled by GC.
