Just to make sure I understand. You're using FindTypes in a DeclContext using
max_matches == 1. But FindTypes will recurse in the DeclContext, so depending
on the actual search implementation, you could have a situation like:
```
class A {
class B {
class C {
};
};
class C {
};
};
```
where if we do depth first we could start recursing down B, find A::B::C which
is a match, note max_matches == 1 and return. So this is really just
FindFirstNestedType, I don't think you can make any claim about directness
given how this is implemented.
I still think the idea of allowing a type search to be limited to a given type
context is useful. We usually do "FindWhatever" returning a list, and
"FindFirstWhatever" returning some not described algorithm's chosen "first"
match. It's a little odd to add the "First" w/o the list version, however.
