Summary SQUIRRELFISH: typeof should return undefined for an undefined variable reference

The expression "typeof x" throws an exception when x is undefined, but it should return undefined instead. This affects the JavaScriptCore regression tests ecma/Expressions/11.4.1.js and js1_5/Array/regress-157652.js.
