GHC Reading Guide

[Sebastian Graf]

Hi Takenobu,

thanks for updating that resource! I know that it was helpful to a couple
of students of mine to get a big picture of GHC.

I don't have anything to add. There are quite a few more -ddump-* flags for
the different Core passes, but I don't think it's interesting to list all
of them on that slide.

Greetings,
Sebastian
