Migrate `HeaderSearch::LoadedModuleMaps` and a number of APIs over to
`FileEntryRef`. This should have no functionality change. Note that two
`FileEntryRef`s hash the same if they point at the same `FileEntry`.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
The FileManager has been updated to return llvm::ErrorOr from getFile
and getDirectory, this commit updates all the callers of those APIs from
clang.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This allows clients to avoid an unnecessary fs::status() call on each
directory entry. Because the information returned by FindFirstFileEx
is a subset of the information returned by a regular status() call,
I needed to extract a base class from file_status that contains only
that information.
On my machine, this reduces the time required to enumerate a ThinLTO
cache directory containing 520k files from almost 4 minutes to less
than 2 seconds.

to determine files that have comnpilation or dependency problems.
A new -display-file-lists option use this to display lists of good files
(no compile errors), problem files, and a combined list with
problem files preceded by a '#'. The problem files list can be
used in the module map generation assistant mode to exclude
problem files. The combined files list can be used during module
map development. See added docs.
