示例1: adjustProfileForInvocationPlugin

* Adjusts the profile for an indirect invocation of a virtual method for which there is an
* intrinsic. The adjustment made by this method is to remove all types from the profile that do
* not override {@code targetMethod}.

* @param profile the profile to adjust
* @param targetMethod the virtual method for which there is an intrinsic
* @return the adjusted profile or the original {@code profile} object if no adjustment was made
