SpeculationReasonGroup

public SpeculationReasonGroup(String name,
                              Class<?>... signature)

Creates a speculation group whose context will always match signature. This constructor is deleted in libgraal to ensure group ids are allocated during build time. Without this invariant, it would possible for 2 different groups to have the same id if the groups are allocated in different libgraal isolates (since static variables are isolate-local).
