// At least one binary has to be provided in |binaries|. Those binaries do not
// have to be valid, but they should be at least parseable.
// The functions can fail due to the following:
// * The given context was not initialised using `spvContextCreate()`;
// * No input modules were given;
// * One or more of those modules were not parseable;
// * The input modules used different addressing or memory models;
// * The ID or global variable number limit were exceeded;
// * Some entry points were defined multiple times;
// * Some imported symbols did not have an exported counterpart;
// * Possibly other reasons.
