This module implements the C code generator.This include file contains the logic to produce constant string and seq literals. The code here is responsible that const x = ["a", "b"] works without hidden runtime creation code. The price is that seqs and strings are not purely a library implementation.Generates traversal procs for the C backend.Code specialization instead of the old, incredibly slow 'genericReset' implementation.Thread var support for architectures that lack native support for thread local storage.

- registerModuleToMain for a module whose cached translation unit is reused: the init/datInit presence comes from the artifact's meta head instead of the (never generated) sections. Mirrors the non-hcr path of registerModuleToMain — reuse is disabled when hcr is on. Source Edit

- Public demand entry: request prc's definition; it is routed to the module that owns it and generated once, exactly as if some generated code had referenced it. Source Edit
