  Log Message:
  -----------
  ThinLTO : Import always_inline functions irrespective of the threshold

Summary: A user can force a function to be inlined by specifying the always_inline attribute. Currently, thinlto implementation is not aware of always_inline functions and does not guarantee import of such functions, which in turn can prevent inlining of such functions.
