    JavaScriptFrameIterator is templatized on the iterator type and renamed to JavaScriptFrameIteratorTemp.
    The original JSFI is now a typedef for JavaScriptFrameIteratorTemp<StackFrameIterator>. Because of templatizing, JSFI code is moved to frames-inl.h
    
    StackTraceFrameIterator moved to frames.*
    
    Implemented SafeStackFrameIterator which wraps StackFrameIterator and have the same interface. It performs additional checks of stack addresses prior to delegating to StackFrameIterator. SafeSFI is used in an another specialization of JavaScriptFrameIteratorTemp template to perform safe JS frames iteration on sampler ticks.
    
    I haven't took an advantage of having multiple stack frames in tickprocessor yet.
