Please review this trivial fix of a format string. The value being printed is
TieredStopAtLevel, which is of type intx, so "%zd" should be used instead of "%d".

Testing: mach5 tier1

Or we can cast it to (int). Or we can change flag's declaration to int type.

Or we can cast it to (int). Or we can change flag's declaration to int type.

I think it's better to change the format string than to cast the value. If we
later change the value type we'll (hopefully by then) get an appropriate
warning about needing to change the format string again. Adding a cast now
becomes a useless or otherwise confusing cast (that is hard to find, because
that's the nature of casts) after a change of type.

I tried changing the type of the option to int and that got messy, because
there are a number of places that are accessing it by name from Java as an
intx, such as using WhiteBox::getIntxVMFlag. I wasn't entirely confident I'd
found all of them, since I was getting into unfamiliar code.
