* sem_ch12.adb (Insert_Freeze_Node_For_Instance): Inst is now
a local variable. Retrieve the related instance when processing
a subprogram instantiation. Such instances appear as wrapper
packages.

* sem_prag.adb (Make_Inline): If the pragma applies to a
subprogram renaming, set inline flags on both the renamed entity
and on the renaming, so that some ASIS queries can be handled
consistently in the absence of expansion.
