Bug 62947 – Don't use PassRefPtr variables in the V8 bindings generator

Don't use PassRefPtr variables in the V8 bindings generator

[Anders Carlsson]

The V8 bindings generator will generate local variables of type PassRefPtr<DOMStringList> and then try to assign into them. This will break when https://bugs.webkit.org/show_bug.cgi?id=62940 is landed so I'll try to remove the offending line in CodeGeneratorV8.pm to see what else breaks. The offending line is

    return "PassRefPtr<DOMStringList>" if $type eq "DOMStringList" and $isParameter;

and it was added as part of https://bugs.webkit.org/show_bug.cgi?id=56950

Anders, are you waiting for something to mark this for review?  It looks fine to me.

With this patch, addSpellcheckRangeCallback in V8HTMLTextAreaElement.cpp now looks like:

+        No new tests. (OOPS!)

^^^ You'll probably want to remove this line from the ChangeLog.
