Merge bitcoin/bitcoin#28999: build: Enable -Wunreachable-code
fa8adbe7c17b16cf7ecd16eb9f3f1792e9da2876 build: Enable -Wunreachable-code (MarcoFalke)
Pull request description:
It seems a bit confusing to write code after a `return`. This can even lead to bugs, or incorrect code, such as https://github.com/bitcoin/bitcoin/pull/28830/files#r1415372320 . (Edit: The linked instance is not found by clang's `-Wunreachable-code`).
Fix all issues by enabling `-Wunreachable-code`.
This flag also enables `-Wunreachable-code-loop-increment`, according to https://clang.llvm.org/docs/DiagnosticsReference.html#wunreachable-code, so remove that.
