[PATCH] D73617: [clangd] Don't mmap source files on all platforms --> don't crash on git checkout

[Sam McCall via Phabricator via cfe-commits]

sammccall added a comment.

Also I'd like to put this onto the 10 release branch because this is a big crasher, fix seems safe, we've run this code on windows for a while.
