The code in https://play.golang.org/p/aYQPrTtzoK now produces the
following stack trace:

goroutine 1 [running]:
main.(*point).negate(...)
	/tmp/go/main.go:8
main.main()
	/tmp/go/main.go:14 +0x23

Previously the stack trace missed the inlined call:

goroutine 1 [running]:
main.main()
	/tmp/go/main.go:14 +0x23

Fixes #10152.
Updates #19348.
