Issue Description

CFE crashes when input contains incorrect usage of super parameters feature instead of reporting a syntax error.

What is the fix

Fix global type inference to propertly handle situations where incorrect super parameters are involved.

Why cherry-pick

Users get an uninformative CFE crash with a stack trace instead of a readable syntax error and can't really figure out what is wrong with their code on their own.

Risk

low
