Fix various tool libraries not to link to clang's .a libraries and dylib

This reverts commit 97aa593a83 as it
causes problems (PR45453) https://reviews.llvm.org/D77574#1966321.
This additionally adds an explicit reference to FrontendOpenMP to
clang-tidy where ASTMatchers is used.
This is hopefully just a temporary solution. The dependence on
`FrontendOpenMP` from `ASTMatchers` should be handled by CMake
implicitly, not us explicitly.

Summary: Adds an option called `AddConstToQualified` to readability-qualified-auto to toggle adding const to the auto typed pointers and references. By default its enabled but in the LLVM module its disabled.

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.
Adds a check that detects any auto variables that are deduced to a pointer or
a const pointer then adds in the const and asterisk according. Will also
check auto L value references that could be written as const. This relates
to the coding standard

Summary:
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.
Patch produced by
for i in $(git grep -l '\\brief'); do perl -pi -e 's/\\brief //g' $i & done
[This is analogous to LLVM r331272 and CFE r331834]

Now that we've moved to C++14, we no longer need the llvm::make_unique

Summary:
Change the namespace for llvm checkers from 'llvm' to
'llvm_check', and modify add_new_check.py and rename_check.py to
support the new namespace. Checker, file, and directory names remain
unchanged.
Used new version of rename_check.py to make the change in existing
llvm checkers, but had to fix LLVMTidyModule.cpp and
LLVMModuleTest.cpp by hand.
The changes made by rename_check.py are idempotent, so if accidentally
run multiple times, it won't do anything.

Summary:
Looks at conditionals and finds cases of ``cast<>``, which will
assert rather than return a null pointer, and ``dyn_cast<>`` where
the return value is not captured. Additionally, finds cases that
match the pattern ``var.foo() && isa<X>(var.foo())``, where the
method is called twice and could be expensive.
.. code-block:: c++
// Finds cases like these:
if (auto x = cast<X>(y)) <...>
if (cast<X>(y)) <...>
// But not cases like these:
if (auto f = cast<Z>(y)->foo()) <...>
if (cast<Z>(y)->foo()) <...>

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.

The include order check would get notified of all include
directives in a depth-first manner. This created the
possibility of an include directive from a header file
interfering with the sort order of a set of two distinct
blocks from the top level cpp file, if that include directive
was on just the right line.
With this patch we bucket the include directives by the file
in which they appear in and process one bucket at a time,
so that directives from different files do not get mixed
together into the same list.
