I'd expect a good JIT to be able to optimize such simple cases, as it could
figure out that the "tmp" variable is not needed.  I think that enable this
basic optimization could speed up considerably a lot of existing code (although
I admit this is just a feeling, it's hard to prove it without implementing

FWIW, the JVM runs the equivalent "slow" code at the same speed of the "fast"
