VM_RECURSION_LIMIT only prevented the recursion of interpreted codeblocks but
native/builtin function calls can also create stack overflow due to the too deep recursion.
This patch fixes#2905.

The reference to the previous context is only used by the debugger and the backtrace info,
so this element should not be part of the structure by default.

This patch reworks the core of the builtin Map object.
Advantages:
- Provide sublinear access time for the elements via Lcache and property hashmap
- This implementation is suitable for the builtin Set object as well
Also add the missing 'forEach' routine for the builtin object as well.

Currently JS objects can only have one native pointer data which could be a limitation in special cases.
This patch allows to register multiple native infos, which can be accessed/associated with the corresponding `jerry_object_native_info_t`.

Binary size gain:
- Intel: ~780B (gcc-7.3)
- Arm: ~450B (arm-linux-gnueabi-gcc-7.3)
The change also contains the renovation of each builtin routine to use early return in case of error to make the code less complicated.

New functions:
- ecma_create_symbol

This patch reduces the number of string to string object conversion during property managing operations,
via access the length property directly from the string instead of the newly created string object.

This patch contains the base functionalities that the new builtin object requires.
Currently unavailable:
- print (Symbol('foo')) - this features requires the refactor of the print handler function
- Several global symbol based builtin routines (follow up patch)

This patch substitutes all binary lvalue operators with an assigment + the corresponding binary operator.
E.g. A += (expression) is pasred as A = A + (expression).
Due to this replacement, all the related binary lvalue CBC opcodes can be removed.
Also the arithmetic related VM instructions can put their result directly onto the stack, since no more checking is needed.

This patch fixes#2658 and ensures that when a class extends value is null and the class has no explicit constructor

also removes the corresponding helpers functions to simplify the instantiation process.

VM_OC_PROP_GET is the general vm instruction for getting an object's property.
This opcode can be mutated into several other opcodes depending on the context (pre- post increment, ident reference).
Since these mutated opcodes perform additional checks and VM_OC_PROP_GET is a highly frequent instruction and it is worth to introduce a special case for it.

This patch removes the ECMA_IS_VALUE_ERROR check from VM_OC_NOT, since the general toBoolean operation cannot throw an exception.

In with contexts the object base value must be resolved before executing a call operation.
Since this happens rarely the base resolving code paths has been seperated to an other VM opcode
so these extra checks do not burden the general property call steps.
JerryScript-DCO-1.0-Signed-off-by: Robert Fancsik [email protected]
The following stucture was highly frequented in the code base:
- Get a builtin object // This operation increases the reference count of the object
- Use it for create a new object
- Deref the builtin object
After a builtin has been instantiated there is always at least one reference to "keep it alive",
so increase/decrease the reference count for getting the value only is unnecessary.

With the change the test file truly checks the corresponding part of the standard (ECMAScript v5, 15.2.3.4.1).

This patch fixes#2587.
The reason of disabling these tests is that the current implementation slightly differs from the related part of the standard (ECMA-262 v6, 9.4.2.3.6.d.1).
This part requires the hidden Symbol.@@species property, hence this functionality has not been implemented yet in the project.
Also add the related test case to prevent further errors.

This patch is the second milestone of the implementation of this new language element.
Supported:
- Single class inheritance
- Functionality of 'super' keyword
- Implicit constructor in class heritage
- Specific behaviour while extending with the built-in 'Array' or '%TypedArray%' object
- Abstract subclasses (Mix-ins)
