-ddump-stg code

[Aaron Tomb]

Actually, that file should be fine. I updated the External Core output  
path to include all of the constructs in modern GHC core. It's the  
input path I've been slow to finish (and, when I do finish it, the  
output format will likely be totally different, too :) )

So, there's little formal documentation of the format, but the files  
can be generated, and you can use them if you like. The document Tim  
pointed to describes something pretty close, but not identical, to  
what it GHC currently generates.

However, I would be wary of investing too much time in writing code to  
process the current .hcr files, because they're likely to change  
significantly in 6.10.
