Merge #6262
6262: Do not spawn redundant hints r=SomeoneToIgnore a=popzxc
Closes #5206
This is a second part of the fix (first was #5997).
This PR adds a new method to the `CompletionContext`: `no_completion_required`. If this method returns `true`, it essentially means that user is unlikely to expect any hints from the IDE at this cursor position.
Currently, checks for the following cases were added:
- Previous item is `fn`: user creates a new function, names of existing functions won't be helpful. Exception for this case is `impl Foo for Bar` -- we must suggest trait function names.
- User entered `for _ i<|>`: it's obviously going to be `in` keyword, any hints here will be confusing.
More checks may be added there later, but currently I've only figured two cases.
