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.

- For non-computed name srcipt functions only identifier/string literal should be set as name
- Implicit class constructor names with non string function name should be ToString-ed

The output of the test262 runner changed between ES5.1 and ES6,
our script should respect it to signal regressions in return code too.

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.

even if no symbols were requested symbols were present in the
resulting array.

We should use the "length" property instead of the internal arraybuffer's length

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.

New method uses length of source to calculate raw string length.
Also bug with template literal was fixed. Template object should have
indexed properties enumerable.

The regexp flag should be correctly referenced and released
if an existing regexp like object is used for constructing a new one.

Template literals already supports escaping backslash and backtick,
this commit enables escaping this in String.raw.
It also fixes invalid behaviour of String.raw when using
new line character.

The release of the regexp pattern string during creating
