### What did you expect to see?
Debug compiler output says
```
./main.go:25:24: PGO devirtualizing d.checker.check to (*c1).check
```
In the objdump of `main.loopVirtual` I expected to see an itab check and conditional direct call (and maybe inlined function body instead of direct method call).

### What did you see instead?

In the objdump of `main.loopVirtual` I  see an unconditional indirect call via DX register
