Split the `InlineHelpers` pass into the three phases: - `link-helpers-to-inline` links the missing `revng_inline` helper bodies from the `libtcg-helpers-to-inline-arch` module. - `inline-helpers` inlines, in every function except those tagged `Root` or `Helper`, the calls to `revng_inline` helpers whose critical arguments on the call site are constant. - `delete-helper-bodies` drops from the module the body of every `revng_inline` function, leaving only the declaration. The three passes live in a dedicated `revngInlineHelpers` library (`lib/InlineHelpers/` + `include/revng/InlineHelpers/`), so that libraries which do not depend on `revngFunctionIsolation` can use them without creating cyclic dependencies.
