Andreas Kling e634fe6072 UserspaceEmulator: Warn on conditional op with uninitialized dependency 
We now track whether the flags register is tainted by the use of one or
more uninitialized values in a computation.

For now, the state is binary; the flags are either tainted or not.
We could be more precise about this and only taint the specific flags
that get updated by each instruction, but I think this will already get
us 99% of the results we want. :^)
