AFAIU, current intrinsics look back at the original Java method shape. So if we limit intrinsics to 
static methods, it would require API-breaking changes in JMH (i.e. users who do explicit 
Blackhole.consume calls), which I hope to avoid. Let's handle instance methods.

...or I misunderstand the suggestion (again).
