RFR: 8199717: Avoid calculating primordial thread stack bounds on VM startup

[David Holmes]

Hi Claes,

I was concerned that this change prevents the primordial thread from 
being able to attach to a VM created on a new thread. But I suppose we 
must assume that if created_by_java_launcher is true then:

a) the VM was not created by the primordial thread; and
b) the primordial thread will not attach to the VM

I still need to check this with the R-Java folk (as the only case I know 
where the VM is created on the primordial thread).

Thanks,
David
