This patch fixes#2779 and the same issue for the Symbol.prototype object, also fixes the check
for the Iterator/ArrayIterator object as well since these checks macro guards were misplaced.

New functions:
- ecma_create_symbol
- ecma_value_is_symbol
- jerry_get_symbol_descriptive_string
Also improve the jerryx_handler_print to be able to print symbol values via using the jerry_get_symbol_descriptive_string API function for symbol values.

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

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.

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.
