[generics] could not find function body in _test packages

[kovetskiy]

go version devel +2dc2987ac87 Tue Jun 23 23:41:16 2020 +0000 linux/amd64

working directory: bug2

bug2_test.go

package bug2_test

import "testing"

func TestT(t *testing.T) {
	x([]int{1}, 1)
}

func x(type T)(v []T, t T) {

}

Error: (the same with go2go test)

> go tool go2go build
could not find function body for "x"

The bug doesn't appear if:
a) I change package name to bug2, or
b) I move x function to another package (and export it)

Change https://golang.org/cl/239708 mentions this issue: [dev.go2go] go/go2go: add IDs for test files

Thanks. This test case, at least, should now be fixed on the dev.go2go branch. I wouldn't be very surprised if there are problems in this area.
