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@bgroup
\o@lign{\relax#1\crcr\hidewidth\ltx@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}
