[TYPO3-core] '=&' can be found all over the code basis

AFAIK there is no such operator and PHP even always creates objects by 
reference. Plus PHP does copy-on-write, thus I do not think that using 
references does any good to performance unless you explicitly have a 
noticeable memory leak or you really need this references.

Taking the linked example, you can just remove the "&" without changing 
anything in the execution of the code.

Please correct me if I am wrong.

Best regards
