    ada: Fix recent assertion failure on GPR2
    
    It's the compiler trying to load the nonexistent body of a generic package
    when trying to inline a call to an expression function of this package that
    has a pre or post-condition (hence the need for -gnata to trigger the ICE).
    
    gcc/ada/
    
            * contracts.adb (Build_Subprogram_Contract_Wrapper): Do not fiddle
            with the Was_Expression_Function flag. Move a few lines around.
