Summary:
I noticed while playing around with
https://github.com/fbsamples/ghc-hotswap/ that the main binary needs to
have a custom main function to set `config.keep_cafs = true` when
initialising the runtime. This is pretty annoying, it means an extra
C file with some cryptic incantations in it, and a `-no-hs-main` flag.
So I've replaced this with a link-time flag to GHC, `-fkeep-cafs` that
does the same thing.
Test Plan:
New unit test that tests for the RTS's GC'd CAFs assertion, and also
the -keep-cafs flag.
