Solidity - v0.8.15

Warning: The release is still in progress and not all binaries may be available yet!

This release fixes two important bugs and also contains other minor bug fixes and features.

For details, please see the release announcement.

Important Bugfixes:
* Code Generation: Avoid writing dirty bytes to storage when copying bytes arrays.
* Yul Optimizer: Keep all memory side-effects of inline assembly blocks.

Language Features:
* Add E.selector for a non-anonymous event E to access the 32-byte selector topic.

Compiler Features:
* LSP: Add rudimentary support for semantic highlighting.
* Type Checker: Warn about assignments involving multiple pushes to storage bytes that may invalidate references.
* Yul Optimizer: Improve inlining heuristics for via IR code generation and pure Yul compilation.

* 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.

We especially thank all the contributors that made this release possible:
