SI-8363 Disable -Ydelambdafy:method in constructor position

As @magarciaEPFL has done in his experimental optimizer [1], we can
avoid running into limitations of lambdalift (either `VerifyError`s,
ala SI-6666, or compiler crashes, such as this bug), by using the
old style of "inline" lambda translation when in a super- or self-
construtor call.

We might be able to get these working later on, but for now we
shouldn't block adoption of `-Ydelamndafy:method` for this corner
case.
