warnings that we want to print only once to the user.  It takes a type
of warning (currently only eWarningsOptimization) and an object
pointer (CompileUnit*) - the warning will only be printed once for a
given object pointer value.

how it goes.  Advanced users will find these warnings unnecessary
noise and will quickly disable them - but anyone who maintains a
debugger knows that debugging optimized code, without realizing it,
is a constant source of confusion and frustation for more typical
debugger users.

I imagine there will be more of these "warn once per whatever" style
warnings that we will want to add in the future and we'll need to
come up with a better way for enabling/disabling them.  But I'm not
srue what form that warning settings should take and I didn't want
to code up something that we regret later, so for now I just added
