[clang-tidy] Merge options inplace instead of copying
Changed `ClangTidyOptions::mergeWith` to operate on the instance instead of returning a copy. The old mergeWith method has been renamed to merge and marked as nodiscard, to aid in disambiguating which one is which.

[clang-tidy] Use vfs::FileSystem when getting config
The config providers that look for configuration files currently take a pointer to a FileSystem in the constructor.
For some reason this isn't actually used when trying to read those configuration files, Essentially it just follows the behaviour of the real filesystem.
Using clang-tidy standalone this doesn't cause any issue.
But if its used as a library and the user wishes to use say an `InMemoryFileSystem` it will try to read the files from the disc instead.

Georgii Rymar 6487ffafd1 Reland "[yaml2obj][ELF] - Simplify the code that performs sections validation."
This reverts commit 1b589f4d4d and relands the D89463
with the fix: update `MappingTraits<FileFilter>::validate()` in ClangTidyOptions.cpp to
match the new signature (change the return type to "std::string" from "StringRef").

Original commit message:

This:

Changes the return type of MappingTraits<T>>::validate to std::string
instead of StringRef. It allows to create more complex error messages.

It introduces std::vector<std::pair<StringRef, bool>> getEntries():
a new virtual method of Section, which is the base class for all sections.
It returns names of special section specific keys (e.g. "Entries") and flags that says if them exist in a YAML.
The code in validate() uses this list of entries descriptions to generalize validation.
This approach was discussed in the D89039 thread.

[clang-tidy] Extend InheritParentConfig to CommandLineConfig
Extend the `InheritParentConfig` support introduced in D75184 for the command line option `--config`.
The current behaviour of `--config` is to when set, disable looking for `.clang-tidy` configuration files.
This new behaviour lets you set `InheritParentConfig` to true in the command line to then look for `.clang-tidy` configuration files to be merged with what's been specified on the command line.

This is useful when using clang-tidy with parallelization command line tools (like ninja and GNU parallel), as they often pipe clang-tidy's standard output and make the colors disappear.

Summary:
Without this patch clang-tidy stops finding file configs on the nearest

results in common parts duplication into every child .clang-tidy file.
This diff adds optional config inheritance from the parent directories

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
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.

Concretely the patch:
 - Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
 - Moves the corresponding unit test from clang to llvm.
 - Moves the vfs namespace from clang::vfs to llvm::vfs.
 - Formats the lines affected by this change, mostly this is the result of
   the added llvm namespace.

AnalyzeTemporaryDtors: false
                       ^~~~~
Error parsing <...>/.clang-tidy: Invalid argument

More so, that error isn't actually a error, the
clang-tidy does not exit with $? != 0, it continues
with the default config.

Surely this breakage isn't the intended behavior.

Richard Smith 02c3baaad2 Fix ODR violations due to abuse of LLVM_YAML_IS_(FLOW_)?SEQUENCE_VECTOR
This is a short-term fix for PR33650 aimed to get the modules build bots green again.

Remove all the places where we use the LLVM_YAML_IS_(FLOW_)?SEQUENCE_VECTOR
macros to try to locally specialize a global template for a global type. That's
not how C++ works.

Instead, we now centrally define how to format vectors of fundamental types and
of string (std::string and StringRef). We use flow formatting for the former
cases, since that's the obvious right thing to do; in the latter case, it's
less clear what the right choice is, but flow formatting is really bad for some
cases (due to very long strings), so we pick block formatting. (Many of the
cases that were using flow formatting for strings are improved by this change.)

Other than the flow -> block formatting change for some vectors of strings,
this should result in no functionality change.
