Fix YA unwanted behavioral difference with operator_precedence_warning.

Jeff Janes noted that the error cursor position shown for some errors
would vary when operator_precedence_warning is turned on.  We'd prefer
that option to have no undocumented effects, so this isn't desirable.
To fix, make sure that an AEXPR_PAREN node has the same exprLocation
as its child node.

(Note: it would be a little cheaper to use @2 here instead of an
exprLocation call, but there are cases where that wouldn't produce
the identical answer, so don't do it like that.)

Back-patch to 9.5 where this feature was introduced.
