Added new test cases to improve branch coverage in Array.prototype routines.
The following script is made for testing branch coverage with all the test suites (--jerry-test-suite --test262 --unittests --jerry-tests), or with only one .js file.

While measuring the branch coverage we dont count JERRY_ASSERT s. The results are measured by running all the test scripts, with the modifications in the PRs.
Branch coverage including pando-project#2682 and pando-project#2674:
-before: 399 / 476
-after: 472 / 476
There are 28 functions in ecma-builtin-array-prototype.c, we hit 14 from them.
The other 14 functions are either already covered, or we could not improve the coverage of it.
More information about the coverage improvement and the branches not reached:

While improving the coverage we found an unnecessary condition check, which can not be false in any cases.

There are quite a few configuration macros in the project.
As discussed in the #2520 issue there are a few awkward constructs.
Main changes:
* Renamed all CONFIG_DISABLE_<name>_BUILTIN macro to JERRY_BUILTIN_<name> format.
* The special JERRY_BUILTINS macro specifies the basic config for all es5.1 builtins.
* Renamed all CONFIG_DISABLE_ES2015_<name> to JERRY_ES2015_<name> format.
* The special JERRY_ES2015 macro specifies the basic config for all es2015 builtins.
* Renamed UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
* All options (in this change) can have a value of 0 or 1.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
JERRY_REGEXP_STRICT_MODE is set to 0 by default.
* Reworked CONFIG_ECMA_NUMBER_TYPE macro to JERRY_NUMBER_TYPE_FLOAT64 name and now
it uses the value 1 for 64 bit floating point numbers and 0 for 32 bit floating point
number.
By default the 64-bit floating point number mode is enabled.
* All new JERRY_ defines can be used wit the `#if ENABLED (JERRY_...)` construct to
test if the feature is enabled or not.
* Added/replaced a few config.h includes to correctly propagate the macro values.
* Added sanity checks for each macro to avoid incorrectly set values.
* Updated profile documentation.
* The CMake feature names are not updated at this point.

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.

This patch fixes#2774 and fixes#2775 as well.
Also add a shortcut to access the length of the array in `ecma_builtin_json_array`.

There was a wrong check on the property types, it did not check that the
property was name accessor. Also fixed a test case.

Added 'JERRY_BIN_OP_INSTANCEOF' to 'jerry_binary_operation_t' and
'jerry_binary_operation'. Added unit tests for this new operation
and updated the documentations.

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 adds posibility to supervise the VM call stack to avoid aborts/crashes due to the recursion calls.

Add missing check for during property handling for %TypedArray% object since until now only string property names were possible.

The regexp engine does not have any recursion depth check, thus it can cause problems with various regexps. Added a new build option `--regexp-recursion-limit N` whose
default value is 0, which is for unlimited recursion depth. Also added a build-option-test.

This patch is the proper fix for #2667, since #2269 did not fix the problem entirely.

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
the proper error is raised during constructing a class instance.

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