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.

Only parsing is implemented, so the async functions currently behave
like normal function except they return with a resolved Promise object
when the function is terminated correctly.

In case of static super member assignments there was a missing
check to validate if the CBC opcode is of CBC_EXT_PUSH_STATIC_SUPER.

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

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

JERRY_ATTR_NOINLINE define is __declspec(noinline) which should be placed
at the beginning of the declaration and caused build fail because it was
placed after the * character. Details can be found here:

This patch implements the core part of let/const statements. Redeclarations are correctly
detected and separate contexts are correctly created for these statements. Register
optimizations are also emplyed whenever possible.
Lots of features are still missing:
- checking the var statements in eval
- const are treated as lets
- single statement checks are missing
- export declarations are exported as vars, let/const export is not supported

The pre-scanner now is able to track all variable declarations and produces a compressed
stream which store this data for each function and catch block. When a function or
catch block is parsed, this information is decoded and the appropriate variables are
created. Furthermore a stack scope is created which contains the currently available
local variables and their register or literal index.
