You can't use latin modern as a test font. In the lmodern fonts the
caps are in a separate file. You have to load them with
SmallCapsFont:

\XeTeXtracingfonts=1

\documentclass{article}
\usepackage{fontspec}
\setmainfont[SmallCapsFont={* Caps}]{Latin Modern Roman}
%\setmainfont{Charis SIL}
\begin{document}
\scshape abc
\end{document}

loads
J:/MiKTeX2.7/fonts/opentype/public/lm/lmromancaps10-regular.otf

Btw: the newest Charis Sil (version 4.106) works fine for me.
