    ada: Remove dead detection of recursive inlined subprograms
    
    Inlining of subprogram calls happens in routine Expand_Inlined_Call
    which calls Establish_Actual_Mapping_For_Inlined_Call. Both routines
    had detection of recursive calls. The detection in the second routine
    was dead code.
    
    gcc/ada/
    
            * inline.adb (Establish_Actual_Mapping_For_Inlined_Call):
            Remove detection of recursive calls.
