Adds support for intrinsics which can be called as stubs. Namely: - HasProperty - MathPow - NewObject - NumberToString - RegExpConstructResult - RegExpExec - Substring - ToString - ToName - ToLength - ToNumber - ToObject Also adds interface descriptors for stub calls which have arguments passed on the stack.
