1812f63fd2 Moved type feedback vector to SharedFunctionInfo. 
Type Vector followup: the type vector currently lives off the code object. This CL moves it to the SharedFunctionInfo, facilitating re-use and continued use in crankshafted code if desired.

bd1fb97d5c Remove Script::SetData and the script_data parameter from Script::(Compile|New). 
This feature makes it possible to associate data with a script and get it back
when the script is compiled or when an event is handled. It was historically
used by Chromium Dev Tools, but not any more. It is not used by node.js.

Note: this has nothing to do with the preparse data, despite the confusing name.
The preparse data is passed as ScriptData*.

Note 2: This is the same as r19616 ( https://codereview.chromium.org/184403002/ )
with a unused variable fix in bootstrapper.cc.

6115a006fd Bugfix for 349874: we incorrectly believe we saw a growing store 
When we set an out of bounds array index, the index might be so large that
it causes the array to go to dictionary mode. It's better to avoid
"learning" that this was a growing store in that case.

This fix also partially reverts a fix for bug 347543, as this fix is
comprehensive and satisfies that repro case as well (partial revert of
v19591).

1fc8ad9486 Fix VPrintHelper used on Windows. 
VPrintHelper would silently ignore the stream given to it if application is in GUI mode (no console is attached) and redirect output to the debugger via OutputDebugString.

Such redirection makes sense only if passed stream is either stderr or stdout. Don't redirect any other stream to the debugger.

Reorder clauses in VPrintHelper to make condition more readable.
