This patch adds a base-class called TemplateInstantiationObserver which gets notified whenever a template instantiation is entered or exited during semantic analysis. This is a base class used to implement the template profiling and debugging tool called Templight (https://github.com/mikael-s-persson/templight). The patch also makes a few more changes: * ActiveTemplateInstantiation class is moved out of the Sema class (so it can be used with inclusion of Sema.h). * CreateFrontendAction function in front-end utilities is given external linkage (not longer a hidden static function). * TemplateInstObserverChain data member added to Sema class to hold the list of template-inst observers. * Notifications to the template-inst observer are added at the key places where templates are instantiated.
