Contains common infrastructural code for both SwiftPM and llbuild.
As this package with time has become a collection of unrelated utilities, that made it much harder to version. Primary users of TSC such as SwiftPM and Swift Driver came up with specialized alternatives to APIs provided in TSC. Moving forward, we don't recommend adding TSC as a dependency to your project. More and more types and functions here will be deprecated, with minimal modifications to ease the migration off TSC.
