[PATCH] D93978: [clangd] DefineOutline doesn't require implementation file being saved

[Nathan James via Phabricator via cfe-commits]

njames93 added a comment.

So I did some tweaking and I have a snapshot filesystem that will hold shared references to the contents, thereby avoiding the need to copy the file contents.
It works for rename and tweaks with no visible issues.
Reasoning behind this a long term goal of letting a user choose between using on disk or dirty buffers when building preambles. 
Obviously there, if using dirty buffers, we wouldn't want to be copying every open file (even unused files) during preamble building/checking.
