TODO:

• Repair CI Repair main and release/5.9 build swiftwasm-build#99
• Prepare Swift SDK artifactbundle
• [Postponed] Implement some critical build system features
  • Experimental Swift SDK integration
  • SwiftPM Build Plugin support (Supported in 5.9.2)
• Check core libraries and tools are compatible with the toolchain
  • JavaScriptKit Swift 5.9 Changes JavaScriptKit#229
  • carton Add 5.9 support carton#412
  • Tokamak: Manually tested with wasm-5.9-SNAPSHOT-2024-01-12-a
• Set 5.9.1 as default value of swift-compiler-version build-script option
  • This step will be unnecessary from the next release, because we can use upstream pre-built toolchain.
• Dispatch distribution workflow

gh workflow run manual-distribution.yml -f run-id=$RC_RUN_ID -f scheme=release-5.9 -f override-name=swift-wasm-5.9.1-RELEASE -f display-name="Swift for WebAssembly 5.9.1 Release $(date +'%Y-%m-%d')" -f display-name-short="Swift for WebAssembly 5.9.1 Release" -R swiftwasm/swift

(Replace $RC_RUN_ID with the GitHub Actions run id for the release candidate build)
