I think we should do this during the inline cost scan, which has a natural thresholding effect. That will also allow us to inline variadic functions where there is a use of 'va_start', but only behind a condition that is known to be false at the callsite we're inlining through.

There are a few other places where we bail out of the cost analysis if we see a construct that simply can't be handled, and it feels like this would fit well there.
