Simplify TurboFan's c1visualizer file handling.
Still having GetTurboCfgFileName in Isolate is ugly, but if we decide that we
don't want to truncate the output file (which would be consistent with
--trace-hydrogen), this could be moved to TurboCfgFile where it actually
belongs.

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.

The issue is that by handling strings with map/handler pairs instead of a special
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
IC would go generic.
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
and non-string types. The choice is either to get that to happen (I don't deem
this necessary from a performance point of view, an IC with such type feedback
before would have gone generic), or simply check for the case of "polymorphic
with some string maps" and require crankshaft to go generic. I'll do the latter.

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.

I think the implementation of ValueOf shows that directly creating the IR does not scale.
