Every evaluation of `globalThis` as a value built an array literal of
every name the global type declares (hundreds of strings) and registered
each one in the known-name table again. A server that reads a singleton
through `globalThis` per request spent about a tenth of its time there.
Emit the name table as one immortal static array per program (the
tagged-template site array, keyed by its contents), and return the
global object at once when the runtime sees a table it has already
registered.
