Speed up creation of Objects whose prototype has dictionary elements

This speeds up both the case from the bug (using Object.create) but also
takes care ofthe "{ __proto__: obj  }" syntax, which was previously (and
erroneously) being treated the same as setting the prototype dynamically
from script using the __proto__ setter or Object.setPrototypeOf.

Update intialization of vtune support.

 In R23940 (https://code.google.com/p/v8/source/detail?r=23940) it introduces
 Isolate::CreateParams and mentions that V8::SetJitCodeEventHandler should either
 be passed to Isolate::New as well, or invoked via the Isolate.

 When Chrome as embedder of V8, we will set the Jit Code event handler for Vtune
 support during the initialization of renderer process and V8 has be initialized
 at that time. It's better that we invoke V8::SetJitCodeEventHander via the Isolate.
 So we change the vTune::InitializeVtuneForV8(v8::Isolate::CreateParams& params) to
 vTune::InitializeVtuneForV8(v8::Isolate* isolate).

 we will do corresponding changes in chromium code if this patch is landed and Chromium
 updates V8 to the
 new release branch.

 some part of this patch is provided by denis.pravdin@intel.com.

version of the keyed load stub (https://code.google.com/p/v8/source/detail?r=24661),
I allowed polymorphism between string and non-string types in the IC. Before, the

Then, at crankshaft time, we special case when we only saw strings. The error
here is that crankshaft can't emit code that handles polymorphism between string

Script streaming: more UTF-8 handing fixes (again).

1) Since we fill the output buffer both from the chunks and the conversion
buffer, it's possible that we run out of space and call CopyCharsHelper with 0
length. The underlying functions don't handle it gracefully, so check there.

2) There was a bug where we used to try to copy too many characters from the
beginning of the data chunk into the conversion buffer. Continuation bytes in
UTF-8 are of the form 0b10XXXXXX. If a byte is bigger than that, it's the first
byte of a new UTF-8 character and we should ignore it.

These two together (or maybe in combination with surrogates) are a probable
reason for crbug.com/420932.

3) The test data was off; \uc481 is \xec\x92\x81.
