[[ UninitialisedVars ]] Update pull request after Peter's comments
Use `MCUnreachable` instead of `MCAssert(false)`, and add a forced exit after it for Release mode (mode in which neither `MCUnreachable` / `MCAssert` have an action) Add `MCAssert(<condition>)` where an `else if (<condition)` statement has been replaced by an `else` statement
