Request for Review (s) - 8133023: ParallelGCThreads is not calculated correctly

GC calls VM_Version::calc_parallel_worker_threads() to determine
the number of GC threads to create.  On Sparc it checks for newer
Niagara hardware to decide the proper scaling of the GC threads with
the hardware threads. calc_parallel_worker_threads() was being called
before enough information was gathered to determine the Sparc hardware.

Moved the gathering of information needed to earlier in the JVM
