Filipp Zhinkin 368f21461c KT-55091 Optimize Sequence::toSet/toList implementation

Sequence::toSet and Sequence::toList both create a
collection, fill it with elements, and then try to optimize a result
by returning empty, singleton, or the allocated collection depending on
the elements count.
Instead of allocating the collection and then trying to return
an optimized instance it is worth checking the sequence's size
beforehand and return empty/singleton collection when possible.

Proposed change optimize performance of aforementioned functions and
also reduce allocation rate when a sequence consists of 0 or 1 elements.

Code Generation for Standard Library

Some of the code in the standard library is created by code generation based on templates. For example, many Array methods need to be implemented separately for Array<T>, ByteArray, ShortArray, IntArray, etc.

To run the code generator use the following command in the root directory of the project:

./gradlew :tools:kotlin-stdlib-gen:run

Note: on Windows type gradlew without the leading ./

This then runs the script which generates a significant part of stdlib sources from the templates authored with a special kotlin based DSL.
