Duncan P. N. Exon Smith e2305f7e90 DebugInfo: Require valid DIDescriptors 
As part of PR22777, switch from `dyn_cast_or_null<>` to `cast<>` in most
`DIDescriptor` accessors.  These classes are lightweight wrappers around
pointers, so the users should check for valid pointers before using
them.

This survives a Darwin clang -g bootstrap (after fixing testcases), but
it's possible the bots will complain about other configurations.  I'll
fix any fallout as quickly as I can!  Once this bakes for a bit I'll
remove the macros.

Note that `DebugLoc` implicitly gets stricter with this change as well,
since it forward to `DILocation`.  Any code that's using `DebugLoc`
accessors should check `DebugLoc::isUnknown()` first.  (BTW, I'm also
partway through a cleanup of the `DebugLoc` API to make it more obvious
what it is (a glorified pointer wrapper) and remove cruft from before
the Metadata/Value split.  I'll commit soon.)

Low Level Virtual Machine (LLVM)
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you're writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
