Reland b9306fd after fixing the issue causing mac builds to fail unittests.
Following on from D77085, I was never happy with the passing a mapping to the option get/store functions. This patch addresses this by using explicit specializations to handle the serializing and deserializing of enum options.

Added some sanity checks to figure out the cause of a (seemingly unrelated) test failure on mac.
These can be removed should no issues arise on that platform again.

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.

The only part of ASTContext.h that requires most AST types to be
complete is the parent map. Nothing in Clang proper uses the ParentMap,
so split it out into its own class. Make ASTContext own the
ParentMapContext so there is still a one-to-one relationship.
After this change, 562 fewer files depend on ASTTypeTraits.h, and 66
fewer depend on TypeLoc.h:
$ diff -u deps-before.txt deps-after.txt | \
grep '^[-+] ' | sort | uniq -c | sort -nr | less
562 - ../clang/include/clang/AST/ASTTypeTraits.h
340 + ../clang/include/clang/AST/ParentMapContext.h
66 - ../clang/include/clang/AST/TypeLocNodes.def
66 - ../clang/include/clang/AST/TypeLoc.h
15 - ../clang/include/clang/AST/TemplateBase.h
...
I computed deps-before.txt and deps-after.txt with `ninja -t deps`.
This removes a common and key dependency on TemplateBase.h and
TypeLoc.h.
This also has the effect of breaking the ParentMap RecursiveASTVisitor
instantiation into its own file, which roughly halves the compilation
time of ASTContext.cpp (29.75s -> 17.66s). The new file takes 13.8s to
compile.
I left behind forwarding methods for getParents(), but clients will need
to include a new header to make them work:
#include "clang/AST/ParentMapContext.h"
I noticed that this parent map functionality is unfortunately duplicated
in ParentMap.h, which only works for Stmt nodes.

This checks finds all primitive type local variables (integers, doubles, pointers) that are declared without an initial value. Includes fixit functionality to initialize said variables with a default value. This is zero for most types and NaN for floating point types. The use of NaNs is copied from the D programming language.

We've been running doxygen with the autobrief option for a couple of

them all.

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.

Removed the uses of the allOf() matcher inside node matchers that are implicit
allOf(). Replaced uses of allOf() with the explicit node matcher where it makes
matchers more readable. Replace anyOf(hasName(), hasName(), ...) with the more

[[ https://bugs.llvm.org/show_bug.cgi?id=39224 | PR39224 ]]
As discussed, we can't always do the transform automatically due to that array-to-pointer decay of C array.
In order to detect whether we can do said transform, we'd need to be able to see all usages of said array,
which is, i would say, rather impossible if e.g. it is in the header.
Thus right now no fixit exists.
Exceptions: `extern "C"` code.

Summary:
The macro may not have location (or more generally, the location may not exist),
e.g. if it originates from compiler's command-line.
The check complains on all the macros, even those without the location info.
Which means, it only says it does not like it. What is 'it'? I have no idea.
If we don't print the name, then there is no way to deal with that situation.
And in general, not printing name here forces the user to try to understand,
given, the macro definition location, what is the macro name?
This isn't fun.
Also, ignores-by-default the macros originating from command-line,
with an option to not ignore those.
I suspect some more issues may crop up later.
