x/tools/gopls: workspace symbols jumps to incorrect location with files with CGO

[jackielii]

Please answer these questions before submitting your issue. Thanks!

What did you do?

source code at https://github.com/jackielii/gopls-bug-report/tree/cgo

.
├── go.mod
├── main.go
└── pkg
    ├── testcgo.go

testcgo.go content:

package pkg

// int one(){ return 1; }
import "C"

func One() int {
	return int(C.one())
}

main.go:

package main

func Hello() {
	panic("not implemented")
}

listing workspace symbols shows Hello properly, however, function One shows:

  One [Function] /home/jackieli/.cache/go-build/d5/d5d064d49f7b917851c19215a835b5b540b3a7e9d446f2381c7d23114aaefaf6-d

What did you expect to see?

expect One to be current workspace, not from build cache

What did you see instead?
