So what's the right way to do this?  There's the regalloc way, which invents
a whole new class just to register register allocators and provide an option
for picking one.  But alias analysis already uses AnalysisGroup so a new class
to register alias analysis passes isn't necessary.

It seems desireable to augment AnalysisGroup with the ability to provide
command-line options.  Is this a good strategy or is there a better way?
