Thomas Lively f6f4f84378 [WebAssembly] Target features section ... Summary: Implements a new target features section in assembly and object files that records what features are used, required, and disallowed in WebAssembly objects. The linker uses this information to ensure that all objects participating in a link are feature-compatible and records the set of used features in the output binary for use by optimizers and other tools later in the toolchain. The "atomics" feature is always required or disallowed to prevent linking code with stripped atomics into multithreaded binaries. Other features are marked used if they are enabled globally or on any function in a module. Future CLs will add linker flags for ignoring feature compatibility checks and for specifying the set of allowed features, implement using the presence of the "atomics" feature to control the type of memory and segments in the linked binary, and add front-end flags for relaxing the linkage policy for atomics.
