Help with JIT talk for tomorrow

[Charles Oliver Nutter]

Thanks for the answers everyone. I updated slides quickly before my
talk to mention the ms times, exception-handling, and OSR sigils.

I'll continue revising the talk over time and adding information.
Probably will add LogCompilation to the list of flags I cover, since
it gives more information than PrintInlining.
