Check SuperPmi map for null
On Linux, calling an instance method with a null `this` pointer causes a seg fault.
This fixes the case of querying the `CanInlineTypeCheckWithObjectVTable` map in SuperPmi when no query has been recorded by `recCanInlineTypeCheckWithObjectVTable`. There appear to be other cases of this, but this is the one that I'm running into currently.
