508e8c234b Fixed #8683 (Using deleted token with multiple template instantiations.) (#1353) 
* Fixed #8683 (Using deleted token with multiple template instantiations.)

* Fixed #8321 (heap use after free: templatesimplifier)

* Add a flag to Token indicating that it has a pointer to it.

* Run dmake

* Fix one source of list pointers to deleted tokens.

Refactor TemplateSimplifier class to get access to template lists.
Remove many function parameters now that they are class variables.
Fix one source of list pointers to deleted tokens.
Add tests with no output to catch crashes.

* Run dmake again.

* Make 2 more functions private.

* Make requested changes.

* Missed one change request.

* Use TokenList rather than Tokenizer.

* Move TokenAndName constructor to cpp file so token.h is not needed in header file.
