auto merge of #11662 : alexcrichton/rust/faster-parens, r=huonw

The included test case would essentially never finish compiling without this
patch. It recursies twice at every ExprParen meaning that the branching factor
is 2^n

The included test case will take so long to parse on the old compiler that it'll
surely never let this crop up again.
