We used to have an optimized version for nodes that are concatenating two strings which was allocating an object on the heap, therefore preventing this code from being executed on the compiler thread. Octane benchmark results show insignificant increase in performance (< 0.5%) without this optimization - see https://docs.google.com/spreadsheets/d/1MC5NrMoMSsqxZqw0ojoZvomBb7q2EOt1S0sFoJ8ld2c/edit?usp=sharing which leads to the conclusion we can safely remove the optimization for now.
