[lworld] RFR: 8311383: Restoring inline class mirrors with CDS.

[Jatin Bhateja]

Inline class encapsulate following two mirror objects
  - Value mirror : primitive value class instance
  - Reference mirror  : primitive reference class instance ( .ref)
 
Currently, runtime allocates and updates java mirror corresponding to a klass in a scratch memory and dumps [1] these into shared archive.  Skipping over allocating inline mirrors into scratch memory for the time being since they can be re-created while restoring unshared fields of inline class[2] during share archive read.
