This isn't a "complete" port of the standard library for embedded Swift, but something that should serve as a starting point for further iterations on the stdlib. - General CMake logic for building a library as ".swiftmodule only" (ONLY_SWIFTMODULE). - CMake logic in stdlib/public/core/CMakeLists.txt to start building the embedded stdlib for a handful of hardcoded target triples. - Lots of annotations throughout the standard library to make types, functions, protocols unavailable in embedded Swift (@_unavailableInEmbedded). - Mainly this is about stdlib functionality that relies on existentials, type erasure, metatypes, reflection, string interpolations. - We rely on function body removal of unavailable functions to eliminate the actual problematic SIL code (existentials). - Many .swift files are not included in the compilation of embedded stdlib at all, to simplify the scope of the annotations. - EmbeddedStubs.swift is used to stub out (as unavailable and fatalError'd) the missing functionality.
