Mads Ager 1f4a3b0d1c [JVM_IR] Avoid safe-call conversions from Byte? and Short? to Int? for
comparisons.

Having those conversions leads to unnecesary boxing and null checks.

This change does it only for JVM in the optimization lowering. It
is unclear to me if the other backends can get away with something
similar.

Dmitry Petrov e1a55e8dec Prefer compact bytecode for primitive/object comparisons with Boolean
'java.lang.Boolean#valueOf' doesn't allocate new objects
(it uses pre-allocated singletons for 'true' and 'false').

Dmitry Petrov 8e9c0294fe Do not box primitives for 'primitive == object'
NB user-defined 'equals' can violate contract for 'Object#equals', e.g.,
it can be asymmetric.
Thus we can't avoid boxing for 'object == primitive'.
