1. Use 'x' for each parameter, which is not an inline class, every possible clash is handled by signature rather than name. This change makes more API changes binary-compatible. So, the changes are in line with the vision of inline classes are value classes, like primitives. 2. Take return type into account when mangling a function if the return type is inline class. Otherwise, boxing bridge will not be generated, which leads to CCE at runtime.
