Preflight admits a createRequire loader's require.resolve call with a
computed request inside a try block, but lowering refused the call, so
in JavaScript source the whole statement became a runtime fence. The
fence threw before the request expression ran, and before anything else
in the statement: `try { where = load.resolve(candidate(name)); }`
skipped candidate()'s side effects, so the catch clause saw a different
state than in Node.
Such calls (a computed request, another argument shape, or
runtime-computed options, on require.resolve and require.resolve.paths)
now evaluate their arguments in order and then throw the fence, as a
computed require call does. The addon-probe fixture checks that a
computed candidate path runs before each failed lookup.
