Description
Implements part of mypyc/mypyc#880.
Implementation for the bytes comparison itself is stolen from the implementation of
bytes_comparefrom cpython and inlined.Later we can switch unicode to use a similar API
Test Plan
Added both IR tests and runtime tests. Made a custom benchmark that yielded performance gain of around 4x (from 2.3x faster to 9x faster than uncompiled vs master).
