emit_escape.ludic: every value is in a class, joined by flow edges (a let, an assignment, an argument
into its parameter, a result into the call) and store edges (a field, an element, a push). HEAP (a
parameter, a state, a global, what an unknown call hands back) flows forward; ESC (stored into
something HEAP, into a global, into an event's fields or named values, handed to an unknown callee)
flows backward, and from an ESC or HEAP target along a store. A load is its base's class. A site that
is neither ESC nor in a function reaching Mem.frame is LOCAL (Node.uns = ES_SCRATCH). ludicc
--escape-report prints each site and the totals; nothing is emitted differently yet - the arena that
allocates the LOCAL sites is next.
@alloc_ok on a generic now covers its instances (kept_push$NetFact is under kept_push's), and a
statement's @alloc_ok is carried on the node (Node.uns), so a generic's clone keeps it.
