Alexander Markov b205ea18cb [vm] Fix compiler crash when returning a value of uninitialized late variable from async function ...

This change fixes CompileType::CanBeFuture() which previously attempted
to use Class objects by class id without first checking if cid is internal.

Cid can be internal (SentinelCid) when CompileType::CanBeFuture() is
called for a return value of an async function when it is returning
a value of an uninitialized late local variable (such Return
instruction is unreachable).
