RFR(M): 8204908: NVDIMM for POGC and G1GC - Updated patch that does not allow AllocateHeapAt and AllocateOldGenAt to be set at the same time...

[Awasthi, Vinay K]

By preventing this, I repurposed _fd_for_heap for NVDIMM mapping. There is now no _fd_for_nvdimm.
JEP to support allocating Old generation on NV-DIMM - https://bugs.openjdk.java.net/browse/JDK-8202286
Here is the implementation bug link: https://bugs.openjdk.java.net/browse/JDK-8204908

Patch is Uploaded at (full patch/incremental patch)

http://cr.openjdk.java.net/~kkharbas/8204908/webrev.01_to_00/
Tested default setup (i.e. no file is being passed for heap) and AllocateHeapAt/AllocateOldGenAt with POGC and G1GC.. all passing...
Any and all comments are welcome!
Thanks,
Vinay
