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').

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'.

1378b0cf05 Fix bytecode tests after new optimizations
- Turn some const conditions into non-const conditions
- Make sure inlined const values are used where required
(otherwise they are eliminated by POP backward propagation)
