<p class="MsoNormal">Following PR 5240 (<a href="http://llvm.org/bugs/show_bug.cgi?id=5240">http://llvm.org/bugs/show_bug.cgi?id=5240</a>), this patch removes LIT’s usage of bash where it can find it. Bash was originally used for performance reasons, but currently
runs show no difference with and without bash, so it makes sense to simplify the code and reduce reliance on external tools.<o:p></o:p></p>
