I think we could consider doing this for any final method with fixed
semantics. For instance, anything in java.lang.Math (taking strictfp
concerns into account, of course). If other final methods are
important for performance, we could inline those too. For instance,
there might be situations where inlining System.arraycopy makes sense.
Implementing this probably wouldn't be very hard. It would make a
nice project for someone wanting to do some gcj front-end hacking.
