Function lateBindMember

test/fixtures/snapshot/typescript.js:57774–57815

* Performs late-binding of a dynamic member. This performs the same function for * late-bound members that `declareSymbol` in binder.ts performs for early-bound * members. * * If a symbol is a dynamic name from a computed property, we perform an additional "late"

(parent, earlySymbols, lateSymbols, decl)
