I think a rtl1 frontend that gets run from a specific subdirectory in 
testsuite/ is probably the best option.

If we're dealing with small snippets, I'm not sure embedding them as 
strings is really that much better than building them up with gen_ 
functions. I'm sure there's room for rtl selftests living inside the 
compiler like that, but anything larger probably ought to live outside.
