Regression test for #63298: inlining a function that
depends on two packages with the same name leads
to duplicate PkgNames.

-- go.mod --
module testdata
go 1.12

-- a/a.go --
package a

func _() {
	a2() //@ inline(re"a2", result)
}

-- a/a2.go --
package a

import "testdata/b"
import anotherb "testdata/another/b"

func a2() {
	b.B()
	anotherb.B()
}

-- b/b.go --
package b

func B() {}

-- b/another/b.go --
package b

func B() {}

-- result --
package a

import (
	b0 "testdata/another/b"
	"testdata/b"
)

func _() {
	b.B()
	b0.B() //@ inline(re"a2", result)
}
