The issue with using a compile command is that it will then work globally. So 
the benchmark would not really test much - besides checking that var handle 
access is slow when `asType` cannot inline. What I was trying to do here was to 
avoid `asType` being inlined into that `compileAsType` method - but I agree 
that the annotation I added isn't it.
