This change allows to use universal equality for combination of signed and unsigned numeric types. It means we can run comparisons like
2 + 2 == 4.toUInt, or-1.toUByte == 255.To allow for that when used in erased context, we modify the NIR generated for
==and!=primitives. These now would delegate toscala.runtime.BoxesRunTime.equalsinstead of delegating to customObject.__scala_==which now becomes obsolete and removed.All numeric equality comparsions are now available between any of
Byte,Short,Int,Long,UByte,UShort,UInt,UByte,Size,USizeandChar.
