To debug utility process crashes, it would be helpful to sub-bucket these processes by type.  For example the high level process type could remain "utility", but the sub-type would be "image_decoder", "extension_installer", "pac_parser", etc.

The code that initializes the process type information seems to be here.

However, I wasn't able to figure out what calls this code for utility processes. Regardless, it seems like a straightforward change.
