1. if an argument of a `pop` cannot be removed, then all other potential arguments of that `pop` can't be removed either, and the same applies to other `pop`s that touch them; 2. the same is true for primitive conversions, but this is even trickier to implement correctly, so I simply did the same thing as with boxing operators: replace the conversion itself with a `pop` and keep the argument as-is. Somehow this actually removes *more* redundant primitive type conversions than the old code in a couple bytecode text tests, so I've patched them to kind of use the value, forcing the instructions to stay. #KT-46921 Fixed
