You need a suitable definition for \=. If the font doesn't has a
suitable accent you will have to build something. E.g this here
would work (but probably not give a good placed bar in all cases,
and it would disable kerning)

\documentclass{article}
\usepackage{graphicx}
\setmainfont[Mapping=tex-text]{Minion Pro}

\makeatletter
\DeclareTextCommand{\d}{\UTFencname}[1]
   {\hmode at bgroup
\o at lign{\relax#1\crcr\hidewidth\ltx at sh@ft{-1ex}.\hidewidth}\egroup}

\catcode`\ṣ=\active
\defṣ{\d{s}}

\DeclareTextCommand{\=}{\UTFencname}[1]
   {$\overline{\mbox{#1}}$}%

\makeatother

\begin{document}
\={a}

Āāīūś  % works as expected.
ṣṇṭḍṃḥ % just crossed out boxes.

\d{s} 

\catcode`\ṝ=\active

\defṝ{\d{\={r}}} ṝ or \defṝ{\={\d{r}}} ṝ

\end{document}
