Summary
The
can_omit_optional_parentheseslayout tries to avoid parenthesizing an expression ifbreaking any of it's sub-expressions that have their own parentheses make the expression fit.
This PR moves the check whether an expression contains any parenthesized expression further up
to ensure we avoid the slightly more expensive layout when there are no other parentheses by which we can break.
