`CallGraphSection` CodeGen option emits the callgraph section. This patch documents the design, implementation and usage of this option and the underlying machinery. Inferring indirect call targets from a binary is challenging without source-level information. Hence, the reconstruction of a fine-grained call graph from the binary is unfeasible for indirect/virtual calls. To address this, CallGraphSection option collects the necessary information to construct the call graph while the source information is present, and stores it in a non-code section of the binary.
