Some things are missing:
 - yield* support
 - generator definition in object literal
 - the hidden GeneratorFunction

47f2f0ea8b General optimizations around compressed pointer management (#3019)
ECMA_GET_POINTER is removed from:
 - property list iteration
 - lexical environment chain iteration
 - prototype chain iteration

For all these iteration the compressed pointer can be used to get the elements and only decompressed them if it is necessary.

- Properly guard ecma property hashmap routines
- Remove the redundant NULL pointer check from ecma_create_property
- Remove ecma_gc_get_object_next since it became unnecessary
- Substitute ECMA_{GET,SET}_POINTER with ECMA_{GET,SET}_NON_NULL pointer when we can assume the pointer is not NULL
- Remove ecma_get_object_prototype and ecma_get_lex_env_outer_reference helper function the reduce the number of NULL pointer checks during decompressing the pointers
- Remove ecma_get_named_accessor_property_{getter,setter} helper functions for also reduce the number of NULL pointer check/decompressions
- Remove ECMA_PROPERTY_SEARCH_DEPTH_LIMIT since in ES5 there is no way to create circular prototype chain, and the ES2015 setPrototypeOf method can resolve this error so this check during the property lookup can be eliminated.

51e3c4455a Implement direct strings. (#2196)
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.

0511091e8a Streamline copyright notices across the codebase. (#1473)
Since the project is now hosted at the JS Foundation we can move to unified copyright notices for the project.

Starting with this commit all future contributions to the project should only carry the following copyright notice (except for third-party code which requires copyright information to be preserved):

"Copyright JS Foundation and other contributors, http://js.foundation" (without the quotes)

This avoids cluttering the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly. Also dropping the year from the copyright notices helps to avoid yearly code changes just to update the copyright notices.

Note that each contributor still retains full copyright ownership of his/her contributions and the respective authorship is tracked very accurately via Git.

dcaec22c0c Major property rework: introducing virtual properties.
Properties are changed to a type and value pair instead of a pointer to an internal
representation. Functions such as ecma_op_object_get_[own_]property do not
return with property pointers anymore.

41337dbd59 Small performance optimizations of the interpreter.
Short summary of the changes:
 - The ecma_reference_t is removed, and its helper functions are deleted.
 - The delete operation does not depend on ecma_reference_t anymore.
 - A new resolve function is added which returns the current value
   of a named binding in the context chain.
 - The vm_op_set_value does not perform type conversions when its arguments
   has the appropriate types.

8c92972b2f Passing less number of arguments to a function is generally faster. So
the three boolean arguments of ecma_create_named_data_property and the
two boolean arguments of ecma_create_named_accessor_property are combined
into one uint8_t argument. On ARM-32 it is preferred to have less than
four arguments, since these arguments can be passed in registers.

c7dcce4fc7 Refactor object property chain to use property pairs. The patch
itself seems a step back, but the primary aim is opening future
optimization opportunities. The list of changes follows:

 - Property is changed to be an abstract type, which has type, flags,
   and a value. It does not have a name anymore and property pointers
   cannot be compressed.
 - Full (32 bit) ecma values can be property values. This allows
   using non-compressed pointers for ecma values in the future.
 - The property chain is not restricted to the same item anymore,
   it can contain hash maps, arrays in the future.
