PHP_CodeSniffer_File::findEndOfStatement sometimes returns end token, but sometimes it returns the last not empty token before that.

E.g. if $start is new:

• in [new Datetime] it returns ].
• in array(new Datetime) it returnsDatetime.
• in new Datetime; it returns ;.

The difference between array() and [] is probably a mistake, because [] was added later in 4df216f, but I don't understand why there's a difference at all.
The examples above are from a sniff that adds () to new. If findEndOfStatement consistently returned the last non-empty statement (like it does for array(new Datetime)), I could insert the () after that.
