Describe the bug

A clear and concise description of what the bug.
A clear and concise description of what you expected to happen.

Steps to reproduce the behavior:

1. When I import some C code using these lines of code, the code navigation stops working. Code:

/*
    struct Receive_return receive_cgo(char* msg, int length, void* p);
	char* send_cgo(void* p);
*/
import "C"

2. When I try to do 'Go to Definition' on an imported interface, it says 'No definition found'
   However, if I remove the quoted code from the top and reload vs code, then code navigation works as expected.

Please take a look at golang/go#35721, as it has more detail about authoring cgo packages using gopls. But first, I would suggest updating to the latest version of Go (1.15). It has a number of cgo-related improvements that enable gopls to work with cgo packages.
