    Array length reduction should throw in strict mode if it can't delete an element. · ed2be747
    ishell authored
    When accessor getter callback is called the v8::PropertyCallbackInfo::ShouldThrowOnError() is always false, since according to ES6 there's no difference between strict and non-strict property loads. For the setter case the v8::PropertyCallbackInfo::ShouldThrowOnError() returns true if the property is set in strict context.
    
    Interceptors follow same idea: for getter, enumerator and query callbacks the v8::PropertyCallbackInfo::ShouldThrowOnError() is always false, and for setter and deleter callback the v8::PropertyCallbackInfo::ShouldThrowOnError() returns true in strict context.
    
    This CL also cleans up the CallApiGetterStub and removes bogus asserts from [arm] Push(reg1, reg2, ..., regN) that prevented from pushing a set of registers containing duplicates.
