- strict functions created using the Function constructor
- generator functions created using the Generator constructor
- async functions created using the AsyncFunction constructor
- functions created using the bind

ES2015 spec made an incompatible change, many builtin prototypes became
no longer valid instances of their respective classes. But unfortunately
it broke the web, so ES2016 reverted String, Boolean and Number prototype
to the original behaviour (ES5.1). JerryScript should match the latest spec.

- ES11 19.3.3 Properties of the Boolean Prototype Object
- ES11 20.1.3 Properties of the Number Prototype Object
- ES11 21.1.3 Properties of the String Prototype Object

The "async" identifier processing is delayed until it is detected that it cannot
be part of an arrow expression. The "async" identifier should be processed at this
point, but it was not happened in this case.

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.

When the getOwnPropertyDescriptor method was invoked the input property
descriptor was not cleared in every case. This could lead to problems when
the property descriptor is not set/modified by the getOwnPropertyDescriptor
call, resulting in a failure at a later state.
Related to this the Proxy getOwnPropertyDescriptor method incorrectly returned
"undefined" value in a single case.
