Make worker-wrapper optional
Add -fworker-wrapper flag which enables the worker-wrapper transformation. It
is implied by -O.
The expected users of this flag, which includes myself, are GHC API users. In
my Haskell-to-Hardware compiler, which uses the GHC API, I have seen no
benifits of the worker-wrapper transformation. It does however induce longer
compilation times.
