Bugfixes:
* ABI Encoder: When encoding an empty string coming from storage do not add a superfluous empty slot for data.
* Common Subexpression Eliminator: Process assembly items in chunks with maximum size of 2000. It helps to avoid extremely time-consuming searches during code optimization.
* Yul Optimizer: Do not remove ``returndatacopy`` in cases in which it might perform out-of-bounds reads that unconditionally revert as out-of-gas. Previously, any ``returndatacopy`` that wrote to memory that was never read from was removed without accounting for the out-of-bounds condition.
