RFR(XS) 8227632: Incorrect PrintCompilation message: made not compilable on levels 0 1 2 3 4

[Vladimir Kozlov]

Hi, Boris

I agree that printing all levels values when particular one is passed is wrong.

I think you should simply print comp_level value because it should be specific in all cases (leaving CompLevel_all check 
as it is and may be adding missing AOT check).

thanks,
Vladimir
