Specify .pre file as requirement if .pre file does not exist to reduce redundant runs

Currently, with the following a.tex (assume folder is empty apart from latexmkrc):

%! TEX program = pdflatex
\documentclass{article}
\usepackage[nofiles]{attachfile2}
\usepackage[attach]{asymptote}
\begin{document}
123
\begin{asy}
    label("45");
\end{asy}

\end{document}

If you type latexmk you get:

tl;dr: Latexmk needs 3 runs.

I propose implementing the following change (or something equivalent, I don't know if this is a good idea, but it's recommended by Ulrike), so it only need 2 runs: In asymptote.sty,

-\InputIfFileExists{\jobname.pre}{}{}
+\InputIfFileExists{\jobname.pre}{}{\typeout{No file \jobname.pre.}}

Result:

vectorgraphics / asymptote

Specify .pre file as requirement if .pre file does not exist to reduce redundant runs #421
