hadrian: add hi_core flavour transformer

The hi_core flavour transformer enables -fwrite-if-simplified-core for
stage1 libraries, which emit core into interface files to make it
possible to restart code generation. Building boot libs with it makes
it easier to use GHC API to prototype experimental backends that needs
core/stg at link time.
