Release Notes: document -f{,no-}integrate-as

Now that the integrated assembler is considered a first class feature of the
compiler and has a proper feature flag, document the change in the compiler
flags.  Ensure that we indicate that the legacy flags are still available, but,
encourage users to switch to the feature flags.
