/**
 * The runtime helper a lowered expression calls, by name. Every one of these is
 * a lookup: the analyzer already decided that this member access is a List
 * `map` or a UInt8Buffer index, and recorded it in `LoweringHints`; what is
 * left is the exported name of the runtime function that performs it.
 *
 * D114 R1c: these were `JavaScriptEmitter` methods beside the expression
 * emission that calls them. They are one cohesive thing — the map from a
 * lowering decision to a runtime name — and both the statement and the
 * expression families read them, so they are their own collaborator.
