Direct strings are a new type of direct ecma-values (no memory allocation is needed for encoding them) in JerryScript. Currently magic strings, external magic strings and uint values are encoded as direct strings. The constant pool of JerryScript byte-code is changed to hold ecma-values rather than cpointers to support direct strings.
