On some platforms, the compiler is allowed to assume that BOOL == bool. On others, BOOL == signed char.
This can cause differences in which bit patterns end up meaning YES or NO. In general, however, 0 == NO and 1 == YES.

To keep it simple, LLDB will now show "YES" and "NO" only for 1 and 0 respectively, and format other values as the plain numeric value instead.
