Make FileEntry::getName() valid across calls to FileManager::getFile()

Because we may change the name of a FileEntry inside getFile, the name
returned by FileEntry::getName() could be destroyed.  This was causing a
use-after-free when searching the HeaderFileInfo on-disk hashtable for a
module or pch.
