without adding a dependency to the core API, so an analysis tool pays
only for the extensions it needs.

The Report function emits a diagnostic, a message associated with a
source position. For most analyses, diagnostics are their primary
result.
For convenience, Pass provides a helper method, Reportf, to report a new
diagnostic by formatting a string.
Diagnostic is defined as:

	type Diagnostic struct {
		Pos      token.Pos

	format, idx := formatString(pass, call)
	if idx < 0 {
		if false {
			pass.Reportf(call.Lparen, "can't check non-constant format in call to %s", fn.FullName())
		}
		return
	}

	firstArg := idx + 1 // Arguments are immediately after format string.
	if !strings.Contains(format, "%") {
		if len(call.Args) > firstArg {
			pass.Reportf(call.Lparen, "%s call has arguments but no formatting directives", fn.FullName())
		}
