nit: update comment

This comment is correct. I didn't move BrowserList::GetLastActive. My rationale
for that is BrowserList has a SetLastActive, so it only seems appropriate to
keep GetLastActive there. OTOH FindLastActiveProfile does more searching, so I
move it.

+// recently open browser owned by |profile| is returned. If none exist, returns
+// NULL.  WARNING: see warnings in BrowserList::GetLastActive().
+Browser* FindLastActiveWithProfile(Profile* profile);
+
+// Returns the number of browsers with the Profile |profile|.
+size_t GetBrowserCount(Profile* profile);
+
+// Returns the number of tabbed browsers with the Profile |profile|.
+size_t GetTabbedBrowserCount(Profile* profile);
+
+}  // namespace browser
