Matthew Dempsky a295d59d10 cmd/cgo: prevent redeclaration of _Ctype_void when C.void is used ... CL 230037 changed cmd/cgo to emit "type _Ctype_foo = bar" aliases for all C.foo types mentioned in the original Go source files. However, cmd/cgo already emits an appropriate type definition for _Ctype_void. So if a source file explicitly mentions C.void, this resulted in _Ctype_void being declared multiple times. This CL fixes the issue by suppressing the "type _Ctype_void = _Ctype_void" alias before printing it. This should be safe because _Ctype_void is the only type that's specially emitted in out.go at the moment. A somewhat better fix might be to fix how _Ctype_void is declared in the cmd/cgo "frontend", but this is a less invasive fix. Fixes #39877.
