While using those tokens inline would result in a parse error, that is not the concern of this sniff. By ignoring these, the sniff causes false negatives. This commit makes the sniff more selective and only ignores inline statements for tokens which are allowed in inline statements. Includes unit test.
The sniff, as it was, only allowed for `or` and `||` logical operators before a termination expression, not for `and`, `&&` or `xor`, while PHP allows these too. See: https://3v4l.org/OWS4n#veol Fixed now. Includes unit tests.
