After talking with a number of people in #llvm, this was the solution  
we came up with.  We couldn't come up with a solution for reporting  
the info from MachineCodeEmitter that didn't require restructuring  
things a lot, so this was the idea we came up with.

One upside is that because it's isolated, we have the ability to  
easily extend it to track more information. One thing I eventually  
want to report is the Relocation information, so that the machine code  
can be manipulated outside of LLVMs control.

I consider it to be a phase 1 of http://wiki.llvm.org/Provide_more_control_over_and_access_to_JIT%27s_output 
, which Jeffrey Yasskin and I have been discussing.

So I guess my point is that I'm open to reporting this data a  
different way, but we haven't yet seen one that is as simple. :)

Additionally, I'm happy to craft this patch externally, but I think it  
would make everyones life easier to get it into the repo, so that  
others can work on adding things to the API.
