// This functionality is implemented by the lib/Bytecode/Reader library.
// This library is used to read VM bytecode files from an iostream.
//
// Note that performance of this library is _crucial_ for performance of the
// JIT type applications, so we have designed the bytecode format to support
// quick reading.
