Description
GCC already has -fdump-go-spec=/-fdump-ada-spec options to write Go/Ada bindings for C/C++.
-fdump-ada-spec is implemented in c-family, so in the FEs; -fdump-go-spec is in the middle-end code, hooking into debug_hooks.

Research direction
Start by reading GCC’s c-family implementation of -fdump-ada-spec and the middle-end implementation of -fdump-go-spec, including its debug_hooks integration. Then identify the rustc_codegen_gcc entry points relevant to equivalent bindgen-like support and define a test for the expected generated bindings; done means the requested binding output is supported.
