    ada: Remove unhelpful special case for renamed bodies in GNATprove mode
    
    This patch reverts a special-case related to inlining of renamed bodies
    in GNATprove mode. Its idea was that inlining is decided in routine
    Cannot_Inline, which is called much later. This didn't quite work,
    because in the meantime the renamed body was prepared to inlining in
    Build_Body_To_Inline, which was not designed to handle renamed bodies.

            * freeze.adb (Build_Renamed_Body): Revert a special case for
            GNATprove; remove unnecessary initialization of a local variable.
