Golang x/tools/cmd/gorename: cannot find Swig identifiers

Please answer these questions before submitting your issue. Thanks!

What version of Go are you using (go version)?

go version go1.9.2 darwin/amd64

Does this issue reproduce with the latest release?

I am using the latest version

What did you do?

In the folder $GOPATH/src/test, I created the following files:

--- main.cxx
#include <iostream>

void SwigTest(int a) {
    std::cout << a << std::endl;
}

--- main.hpp
void SwigTest(int a);

--- main.swigcxx
%{
#include "main.hpp"
%}

%include "main.hpp"

--- test.go
package main

var val = 42

// Test just call the swig function SwigTest
func main() {
    SwigTest(val)
}

and I ran:

gorename -from test.go::val -to value

What did you expect to see?

I expected val to be renamed into value. (And this actually works if I comment the line SwigTest(val) of test.go).

What did you see instead?

/Users/fbenhamo/go/src/test/test.go:7:2: undeclared name: SwigTest
gorename: couldn't load packages due to errors: test

Note: the previous example compiles (go build) and run perfectly well. Only gorename cannot find the symbol SwigTest declared by swig.
