…tandard library. Older versions of the 5.8 compiler have a bug when generating SIL for functions with `@_backDeploy` containing defer blocks (swiftlang#62444) and for now we need the standard library interface to be compatible with those older compilers. Resolves rdar://104045168

All compilers that must be able to compile the standard library's textual interface accept the following: - back deployed functions declared without `@available` - `@inlinable` back deployed functions - `defer` blocks in back deployed functions We can therefore revert the workarounds added in swiftlang#62946 and swiftlang#62928.
