test(wasm): exceptions in a wasm build, and a sysroot without them WasmExceptions builds a fixture for wasm32-wasip1 and runs it under wasmtime. It throws through four frames whose destructors have to run, catches the exception, catches one that vector::at throws, and with an argument lets one escape main, which has to fail the run. With the previous flags the fixture does not compile ("cannot use 'throw' with exceptions disabled"), and each part of turning exceptions on fails it in its own way, from a BMI built without them to the legacy encoding wasmtime refuses. WasiSysrootWithoutExceptions takes a scratch sysroot through three states, no libunwind, libunwind under eh/ and libunwind in the triple's own directory, and checks that only the first stops the build, with the message naming the library it looked for. It needs no working wasm toolchain, so it also runs where the others skip. WasmHelloRuns and WasmExceptions treat a sysroot without the exception-enabled libraries as missing and skip. The manifest tests expect the exception-handling probe on every entry. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> 2026-10-31 05:54:48 +01:00			`// SPDX-License-Identifier: LGPL-3.0-only`
