PPC: [deoptimizer] Basic support inlining based on SharedFunctionInfo.

Port cf21da7e

Original commit message:
Up until now we can only inline based on JSFunction, because of the way
the deoptimization works.  With this change we will be able to inline
based on the SharedFunctionInfo and materialize the JSFunction from a
literal or a stack slot when necessary.
