What?

Performance and memory fixes during creation of the module graph

-30% memory on module graph, -20% runtime on module graph

  • fix apply_esm_specific_options caching
  • avoid resolve task for get_exports
  • avoid analyse created items being turbo-tasks functions
  • avoid reading created Vc
  • determine module type per directory
  • reduce resolve tasks
  • make some functions in module processing non-turbo-tasks-functions, avoid reference type in apply_module_type
  • add Option<Vc>::to_resolved
  • make esm_resolve a normal function
  • make resolve_asset a non-turbo-tasks-function

Closes PACK-3775
