LOG: [flang] Feature list plugin
Plugin that counts the number of times each tree node occurs in a given program. Used for test coverage.
> One thing we need...is a way to determine what features a code uses. Preferably we would also be able to determine if they are implemented or not. Just the former could be done with a visitor for the parse tree. For the latter we would continue compilation and somehow ignore todo errors but collect them - @jdoerfert
