Nico Hartmann 43997d3ac6 [TurboFan] Transition SharedFunctionInfo to kNeverSerialized (2) 
This is the 2nd step in series of CLs to move the SharedFunctionInfo
class to kNeverSerialized and make it concurrently accessible from
the background thread. This CL:
* Changes optimization of GetTemplateObject in JSCreateLowering to
  only perform the optimization of a template object exists in the
  SharedFunctionInfo[Ref], but skips the optimization if one is
  missing instead of allocating a new one on demand.
