Frontend: For whole module compiles, omit filelists from stack dumps. For batch compile jobs, it's helpful to see which files are considered primary and that was the original reason why filelist contents were printed in compiler crash stack dumps. However, for whole module compile jobs, the contents of the filelist is uninteresting (it's just all the files in the module) and can be hundreds or thousands of lines long so it often causes important information to be trimmed from stack dumps received in reproducers.
