This patch fixes#4446.

- Rework symbols to have the same value across realms
- Support realms for native functions
- Support test262
- Use new.target realms for constructing intrinsics

- Type for realm objects is introduced (ecma_global_object_t)
- Realm reference is added to built-in objects and ECMAScript functions
- Resolving built-ins, global environments, and scopes require realm object
- Unnecessary global object accesses are removed from the code
Missing: external functions and static snapshot functions have no realm reference

The previous `ecma_is_constructor` implementation did not checked if the
target function was an arrow or generator function. This resulted in
an incorrect execution for these function types.

After ES5.1 if the delete returns false a TypeError should be thrown
in strict mode.

A new shared frame context data is created which allows sharing
data between the function call and vm main loop. Furthermore
rest arguments and current function object handling is reworked.

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

In case of Proxies the "ownKeys" call can return an incompatible
value for a for-in statement. In such cases the error should be
propagated to the user.
Fixes: #4159

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

From ES 6 the ToPropertyKey operation is used to convert elements to a valid property key.
This "new" method uses the ToPrimitive operation which can call the `@@ToPrimitive`
well-known symbol to convert the given element to a key.

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.

During the `opfunc_spread_arguments` argument release process
the stack pointer was incremented early resulting in a state where
one of the arguments was not freed causing a memory leak.

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.

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
JerryScript-DCO-1.0-Signed-off-by: Robert Fancsik frobert@inf.u-szeged.hu
- Internal routines of the of the proxy object are unimplemented
- For-in enumerate with proxy target is currently not supported

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.

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
