- this binding in static fields are not supported
- static field evaluation order is wrong
- function names are not supported

I've removed the ecma_op_object_get_property_names method, and implemented the following ones:
- ecma_op_object_own_property_keys: this is now the internal [[OwnPropertyKeys]] method
- ecma_op_object_enumerate: this is used for the for-in iterator
- ecma_object_sort_property_names: this is used for sorting the property names of an object
- ecma_object_list_lazy_property_names: this is for getting the lazy instantiated properties
- ecma_object_prop_name_is_duplicated: this is for checking if a given property is duplicated in an object
Also the for-in operation with Proxy object works with this patch, #3992 should be closed

Now the following conventions are applied:
- passing the number of arguments for a function call is always uint32_t
- string size/length/position related operation should use lit_utf8_size_t
- Extended objects internal fields must be uint32_t

The previously allocated property should not be deleted only it's type should be change.

A list of changes:
- 'es2015-subset' profile is deprecated, and an 'es.next' profile is added.
- The default profile is changed to 'es.next'
- Renamed the JERRY_ES2015 guard to JERRY_ESNEXT
- Renamed JERRY_ES2015_BUILTIN_* guards to JERRY_BUILTIN_*
- Moved es2015 specific tests to a new 'es.next' subdirectory
- Updated docs, targets, and test runners to reflect these changes
Resolves#3737.

In ES2015 many builtin prototypes are no longer valid instances of their
respective classes. This change updates affected prototypes to be
regular objects as required.

Until now JERRY_CONTEXT_INVALID_NEW_TARGET was used to represent whether the eval called from the script directly.
This information can be retrieved from the parser, so it simplifies the runtime handling of the new.target.
This patch fixes#3630, fixes#3640 and fixes#3641.

The following methods have been implemented:
- RegExpAlloc, based on ECMA-262 v6, 21.2.3.2.1
- RegExpInitialize, based on ECMA-262 v6, 22.2.3.2.2
- RegExpCreate, based on ECMA-262 v6, 21.2.3.2.3

Currently, collections use object based solutions for storing elements and
iterating on them. If an element is deleted and re-inserted, the storage
position is the same as before so the iteration order is wrong.
This patch replaces the object based storage with an array based solution
that helps to store and iterate elements as expected.

Changes:
- Use the pre-scanner to provide information for the parser about the existence of the class constructor
- The allocation of the super declarative environment is no longer needed
- The VM frame context holds the information about the this binding status
- Reduce the number of class related VM/CBC instructions
- Improve ecma_op_function_{construct, call} to properly set new.target

Fixed:
- Global symbol access
- Array.prototype.values and Array.prototype[Symbol.iterator] must be the same function object
To test the new functionality arguments object Symbol.iterator property is added.

Notable changes:
* Extracted the pure JS/builtin and external C method invocations
into two new methods (`ecma_op_function_call_{simple, external}`).
* Updated parser/scanner to handle "new.target" correctly.
* Added JS test case.

There is no need for a specific opcode after yield because
the return and throw commands can be redirected to fake byte code sequences.

Still missing: create lexical environment for automatic module conversion.
