Similar to https://dart-review.googlesource.com/c/sdk/+/445540 this
avoids compilation timeouts by avoiding recompiling the receiver in long
chains of invocations.
Guards all of the soundness checking behind a single generation check.
This was already true for nested calls but not for chains of invocations.
This also resolves a correctness issue where sub expressions of the
receiver in chained calls would be evaluated multiple times at runtime.
