    d: Fix regression, all 32-bit execution tests FAIL: internal error printing module cycle
    
    For 32-bit btr(), BIT_NOT_EXPR was being generated twice, something that
    was not seen with the 64-bit variant.  Removed the second call to fix
    the generated code.
    
    gcc/d/ChangeLog:
    
            PR d/96393
            * intrinsics.cc (expand_intrinsic_bt): Don't generate BIT_NOT_EXPR for
            btr32 intrinsic.
