Instead of hacking into the babel plugin passes, this now takes a new approach for the HIR tab: - The different passes are exported from the babel plugin (for simplicity) - The tab actually runs the compiler steps based on local config in the tab. - Re-purposed the CompilerFlags component to configure what passes to run. This is currently mostly causing different errors, but could be useful going forward as a direction.
