The checked-dynamic tier needs two more optional units: Array.prototype's
generic algorithms over array-like receivers (scr_dyn_array_like.c) and the
Number/Boolean prototype objects as values (scr_dyn_builtin_prototype.c).
Both are listed as optional runtime sources under a predicate of their own
(all(<feature>, "dynInvoke")), so they link only into a program whose IR
uses the matching libCall, and neither is an always-linked unit. Their
symbol prefixes are in DYNAMIC_TIER_PREFIXES, so a fully typed executable
may not carry them either.
