Hi Tom, adding a bunch of testcases that diff against binary blobs seems like a
really bad idea to me.  Suppose I make a change to codegen and one of these
tests breaks.  How am I to understand if the change I made just resulted in an
unimportant difference, such as slightly different register allocation, or if
I really broke something?

Ciao, Duncan.
