Multiple test failures (regressions with miscompiles?) with swift-DEVELOPMENT-SNAPSHOT-2025-12-11-a on Linux

Failures need to be reduced and potentially reported as compiler bugs on swiftlang/swift

E.g.

✘ Test runWithTokenThreading(test:) recorded an issue with 1 argument test → Vendor/testsuite/const.wast at SpectestTests.swift:32:10: Caught error: Vendor/testsuite/const.wast:673: invoke result mismatch: expected: [WasmTypes.Value.f32(1)], actual: [WasmTypes.Value.f32(0)]
