A shorthand property's name carries the property's symbol, so the
identifier lowering's typed-array and NaN/Infinity cases, which checked
that symbol's provenance, did not match `{ Uint8Array }` or `{ NaN }`. A
JavaScript source stored the opaque identity token there, and TypeScript
stored a runtime fence; the long form `{ Uint8Array: Uint8Array }` read the
constructor. Both cases now resolve the name as the other builtin cases do
(isStdlibGlobal), which reads the shorthand's value symbol.
In JavaScript sources, `globalThis.NaN` and `globalThis.Infinity`, and
destructuring them from the global object, read the identity token too.
They now read the numbers.
