Haojian Wu 66ace4dc02 [clang-tidy] Fix a nullptr-access crash in unused-raii-check.
I saw this crash in our internal production, but unfortunately didn't get
reproduced testcase, we likely hit this crash when the AST is ill-formed
(e.g. broken code).

Michał Górny 8018e7b447 [lldb] [Process/FreeBSDRemote] Fix regset names and related tests
Restore Linux-alike regset names for AVX/MPX registers

TestRegisters to be aware that they are not available on FreeBSD
and NetBSD, at least until we figure out a better way of reporting
unsupported register sets.

Michał Górny 9367b57dad [lldb] [test] Fix qRegisterInfo lldb-server tests to handle missing registers
Fix qRegisterInfo tests to handle Exx error response when querying
registers that are not supported on the platform in question.  This
is how FreeBSD and NetBSD platforms reporting missing registers right
now, and there certainly is value from verifying the remaining
registers.

This change fixes the test for FreeBSD but NetBSD has other regressions
that still need to be researched.

Compilation logic for External blocks. A few of the high level points:
- Requires exactly one-of File/Server at a time:
  - Server is ignored in case of both, with a warning.
  - Having none is an error, would render ExternalBlock void.
- Ensures mountpoint is an absolute path:
  - Interprets it as relative to FragmentDirectory.
  - Defaults to FragmentDirectory when empty.
- Marks Background as Skip.

Aaron Puchert 1a009296a4 Build reproducible tarballs for releases
Currently the tarballs contain superfluous metadata, like the user name
of the packager and via Pax headers even the PID of the tar process that
packaged the files. We build the monorepo projects directly from the git
repo using "git archive" and for the test-suite we add some flags as
recommended by https://reproducible-builds.org/docs/archives/. We don't
use numeric owners though to be compatible with "git archive".

The advantage of "git archive" is that the releaser doesn't have to
download the tar ball and extract it, rather the archive is built
directly from the repository. This is probably what GitHub uses
internally to produce the tarballs, so I wouldn't expect a difference.

Ella Ma 1756d67934 [llvm][clang][mlir] Add checks for the return values from Target::createXXX to prevent protential null deref
All these potential null pointer dereferences are reported by my static analyzer for null smart pointer dereferences, which has a different implementation from `alpha.cplusplus.SmartPtr`.

The checked pointers in this patch are initialized by Target::createXXX functions. When the creator function pointer is not correctly set, a null pointer will be returned, or the creator function may originally return a null pointer.

Some of them may not make sense as they may be checked before entering the function, but I fixed them all in this patch. I submit this fix because 1) similar checks are found in some other places in the LLVM codebase for the same return value of the function; and, 2) some of the pointers are dereferenced before they are checked, which may definitely trigger a null pointer dereference if the return value is nullptr.
