The MozJSImplScope::buildStackString() function is used to make the hang_analyzer.py script log the JavaScript stacktrace at the time the test has hung. We shouldn't upgrade the MongoDB toolchain to clang-6.0 if it is going to reduce the diagnostics that are available to a Server engineer when an Evergreen task times out.
