Reviewed by Filip Pizlo.

Source/JavaScriptCore:

The bug was caused by BytecodeGenerator trying to generate "super" expression inside the constructor of a base class.
Disallow that by keeping track of whether "super" has been used in the current scope or not (needsSuperBinding flag)
and then throwing a syntax error in parseFunctionInfo if it was used and the current scope wasn't the constructor of
a derived class.

* parser/Parser.cpp:
(JSC::Parser<LexerType>::parseFunctionInfo): Don't allow super() or super.foo outside the constructor of a derived class.
(JSC::Parser<LexerType>::parseClass): Pass in the constructor kind to parseGetterSetter.
(JSC::Parser<LexerType>::parseGetterSetter): Ditto to parseFunctionInfo.
(JSC::Parser<LexerType>::parseMemberExpression): Set needsSuperBinding flag true on the containing scope.
* parser/Parser.h:
(JSC::Scope::Scope):
(JSC::Scope::needsSuperBinding): Added.
(JSC::Scope::setNeedsSuperBinding): Added.

LayoutTests:

Added more test cases to an existing test.
