Nicholas Piggin e15a4fea4d powerpc/64s/hash: Add some SLB debugging tests ...

This adds CONFIG_DEBUG_VM checks to ensure:
  - The kernel stack is in the SLB after it's flushed and bolted.
  - We don't insert an SLB for an address that is aleady in the SLB.
  - The kernel SLB miss handler does not take an SLB miss.
