Bug description:Return in a finally clause silently ignores an exception thrown in a try clause

Description:
------------
Return in a finally clause silently ignores an exception thrown in a try
clause.
I understand that there is no way to handle an exception here, but it
MUST NOT be silently dropped out.

The interpreter should trigger an E_NOTICE or something similar here.

Looks like any version of PHP from 5.6 to 7.1.4 behaves in the same
manner: https://3v4l.org/C16rP

Here is a similar issue: https://bugs.php.net/bug.php?id=68270

Test script:
---------------
<?php

class MyException extends Exception
{
    public function __construct($message = "", $code = 0, Throwable
$previous = null)
    {
        print "2. Exception constructor\n";
        parent::__construct($message, $code, $previous);
    }
}

function ololo() {
    try {
        print "1. Start\n";
        throw new MyException("4. Exception message\n");
    } finally {
        return "3. Return statement\n";
    }
}

try {
    print ololo();
} catch (Exception $e) {
    print $e->getMessage();
}

Expected result:
----------------
1. Start
2. Exception constructor
PHP NOTICE: Dropped exception due the return statement in a finally
block
3. Return statement

Actual result:
--------------
1. Start
2. Exception constructor
3. Return statement
