Symbols for type cells. We can make more efficient code to check against type cells in the future if we use symbols, guaranteed not to conflict with user code. Currently, the "symbols" are the hole and undefined. Undefined may come in from the outside.

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.

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).

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.

If the replacer array contains a property key we should include the
property even if the property is non enumerable or if it is a non own
property.

String and Number wrappers in the replacer array should be treated as
string and number values.
