fillreturns: suggest fixes for errors due to an incorrect number of return values

This checker provides suggested fixes for type errors of the type "wrong number of return values (want %d, got %d)". For example:

func m() (int, string, *bool, error) {
	return
}

will turn into

func m() (int, string, *bool, error) {
	return 0, "", nil, nil
}

This functionality is similar to https://github.com/sqs/goreturns.
