Request for Review (vs) - 8034056: assert(_heap_alignment >= _space_alignment) failed: heap_alignment less than space_alignment

8034056: assert(_heap_alignment >= _space_alignment) failed: 
heap_alignment less than space_alignment

In the calculation of the heap alignment there was an exception for the
UseParalelGC collector for the case of large pages.  The fix was to remove
that  exception.

Fixed was tested on a machine that exhibited the failure
