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.

A single promise can be resolved any number of times due to
thenable functions, but each resolver pair can only be called once.

When appending the key/value pair separately, garbage collection could be
triggered before the value is added, which could cause problems during
marking. This patch changes insertion to add both values at the same
time, which prevents partial entries from being present in the internal
buffer.
Fixes#3804.

Property key query for Proxy objects always returned all keys
even if no symbols were requested symbols were present in the

Also a minor update to the FromPropertyDescriptor operation since in ES6 we can use a property
descriptor whitout any keys

This patch reworks several structures:
- Fulfill and reject reactions are combined into one collection. The values in this collection
are compressed: a capability followed by an optional fulfill and reject functions.
- Fulfill and reject reactions are directly stored, no need to allocate an object for them.
- The job queue directly stores its items, this saves a pointer to the value, and the
callback is replaced by an uint8 type.
- Promise status and already resolved is stored in extra_info.

When lastIndexOf is executed the array length can change and in
case of fast arrays the length should be re-checked.

The release of the regexp pattern string during creating
was incorrect as it was dereferenced a bit to early.

Fixes two bugs in the index calculations that affect the result
of the `String.startsWith` function:
- Fixes the implementation of ECMA-262 v6, 21.1.3.18, step 14:
"If searchLength+start is greater than len, return false".
- Fixes the return value of the helper function
`ecma_builtin_helper_string_find_index`. If it is called with a
starting search position, the returned index should be
not less than that.
These changes fix the following test cases in the test262 suite:
- built-ins/String/prototype/startsWith/return-true-if-searchstring-is-empty.js
- built-ins/String/prototype/startsWith/searchstring-found-with-position.js

In ES6 accessors of built in object are by default configurable.
Also lastIndex property of RegExp object is created when only used.

During ecma_collection_append the underlying collection
was not increased in the required case. This triggered
a buffer overflow when processing the bound function's arguments
during call or during the Proxy ownKeys method.
