Semi-colon spacing

[colinodell]

c8a5646 should be reverted. However, this would prevent semi-colon usage like this:

function test() {
    $x = $whatever
        ->foo()
        ->bar()
    ;
}

So we need to make an expection for this case, which might require us making our own version of SemicolonSpacingSniff

Or we could just disallow that example above?
