d0e0ff01ad Revamp v8_optimized_debug options 
This patch changes the definition of v8_optimized_debug==1 to match the release-mode compiler optimization settings (generally, going from -O1 to -O3 on Linux, similar switches for Mac/Win). This produces a minor speed up on Linux, but significant speedups on Mac and Win. This may make it much harder to debug, though.

It also adds a v8_optimized_debug==2 that, in addition to the compiler optimizations, undef's DEBUG and defines DEBUG. This leaves V8_ENABLE_CHECKS alone (so that the assertions are still enabled), but otherwise basically matches a release mode build.

Builds with v8_optimized_debug==2 roughly match a Release mode build for speed; the V8_ENABLE_CHECKS checks appear to have minimal performance impact (maybe 5-10%, unlike what was previously thought). In addition, switching from the previous optimization settings makes a significant improvement on Mac and Win (50% or more), and switching from DEBUG to NDEBUG makes a significant improvement (another 50% or more).

Note that using v8_optimized_debug==2 may also cause some v8 tests to fail. This is currently is believed to be acceptable.

2fe3799b8f Added unit tests for the slightly confusing Boolean/BooleanObject API. 
Just for documenting the status quo. As discussed offline, we should
probably rename/deprecate a few things:

  NumberObject::NumberValue() => NumberObject::ValueOf()
  BooleanObject::BooleanValue() => BooleanObject::ValueOf()
  StringObject::StringValue => StringObject::ValueOf()

837276829e Fix HasResult method of LTemplateInstruction to properly handle LCheckSmi 
LCheckSmi sometimes has a result register and sometimes not, even though its
LTemplateInstruction alwasys has room for one. Debug output use HasResult to
determine whether it was ok to de-ref result(), but HasResult doesn't check for
the case where LTemplateInstruction has a result but it's NULL.

e9cc78af7e Fix for V8 issue 2795: Check fails with deopt for mjsunit/array-store-and-grow 
(https://code.google.com/p/v8/issues/detail?id=2795)

The reason is when allocating and building arrays in hydrogen we need to ensure
we do any int32-to-smi conversions BEFORE the allocation. These conversions can
at least theoretically deoptimize. If this happens before all the fields of the
newly allocated object are filled in, we will have a corrupted heap.

141ada02f2 Logger: introduce abstract interface for CodeEvent listeners. 
New abstract class CodeEventListener was created.

CodeEventLogger which is the base class for Jit, LowLevel
and CodeAddressMap loggers was inherited from CodeEventListener.

CodeAddressMap class was moved to serializer.cc because serializer is the only user for it. Actually it collects code names and pushes them to the standard log as SnapshotCodeNameEvent. So I extracted this code into separate function CodeNameEvent. It happens that this method works only when Serializer serializes an object. So I added direct log call there.

CodeEventLogger class declaration was moved to the header
because CodeAddressMap needs it.
The code for the nested class CodeEventLogger::NameBuffer was left in the cc file.

CpuProfiler now is inherit CodeEventListener but not used
the loggers infrastructure yet due to the complex initialization schema. I'd like to fix that in a separate cl.

372763897d Lazy call to custom stack trace formatting using Error.prepareStackTrace. 
This enables custom stack trace formatting for stack overflow.
A consequence is that stack trace formatting is now easily observable,
but we already established that the default stack trace formatting can
be observed anyways. It is only triggered by the .stack getter, and
it has to be explicitly called, (e.g. not implicitly after GC).

3c9efdeeb4 Migrate more tests from blink repository. 
The stand-alone test driver is changed a bit:
- Don't use the errorMessage list. It is used differently in the embedded driver. There it collects parser errors - instead of failure messages.
- Remove html links in description texts. Some test descriptions print a web reference.

The migrated tests fall into 3 categories:
1. Tests outside fast/js
2. Tests that print FAIL messages (and also expect those) - these tests should be examined later if they make sense at all
3. Tests with html links in the test description
