The compiler currently has two modes for compilation: one where it compiles each function as it sees them, and another where it enqueues them all into a work queue. A subsequent CL is going to reorder function compilation to ensure that functions are always compiled before any non-trivial function literals they enclose, and this will be easier if we always use the compile work queue. Also, fewer compilation modes makes things simpler to reason about.
