cmd/compile: error line:col information points to wrong function parameter

[yansal]

Does this issue reproduce with the latest release?

Yes

What did you do?

https://play.golang.org/p/6PRJL3-x2lO

What did you expect to see?

An error like prog.go:8:2: cannot use bad (type func() func()) as type func() in argument to f

What did you see instead?

prog.go:7:4: cannot use bad (type func() func()) as type func() in argument to f

The compiler error line:col information points to the first argument, but the actual error is the second.

Thanks for the report.

This is essentially a dup of #15459.
