Returns an array of callsite objects with the following methods:

getTypeName: returns the type of this as a string. This is the name of the function stored in the constructor field of this, if available, otherwise the object's [[Class]] internal property.
getFunctionName: returns the name of the current function, typically its name property. If a name property is not available an attempt will be made to try to infer a name from the function's context.
getMethodName: returns the name of the property of this or one of its prototypes that holds the current function
getFileName: if this function was defined in a script returns the name of the script
getLineNumber: if this function was defined in a script returns the current line number
getColumnNumber: if this function was defined in a script returns the current column number
getEvalOrigin: if this function was created using a call to eval returns a CallSite object representing the location where eval was called
isToplevel: is this a top-level invocation, that is, is this the global object?
isEval: does this call take place in code defined by a call to eval?
isNative: is this call in native V8 code?
isConstructor: is this a constructor call?
