[clang-tidy] Exclude template instantiations in modernize-use-override

Added IgnoreTemplateInstantiations option to modernize-use-override
check. Allows to ignore virtual function overrides that are part of
template instantiations. This can be useful in cases where the use
of the "override" keyword is not appropriate or causes issues with
template specialization.

Fixes #38276.

There's many instances in clang tidy checks where owning strings are used when we already have a stable string from the options, so using a StringRef makes much more sense.

[clang-tidy] modernize-use-override new option AllowOverrideAndFinal

Summary:
In addition to adding `override` wherever possible, clang-tidy's `modernize-use-override` nicely removes `virtual` when `override` or `final` is specified, and further removes override when final is specified. While this is great default behavior, when code needs to be compiled with gcc at high warning levels that include `gcc -Wsuggest-override` or `gcc -Werror=suggest-override`, clang-tidy's removal of the redundant `override` keyword causes gcc to emit a warning or error. This discrepancy / conflict has been noted by others including a comment on Stack Overflow and by Mozilla's Firefox developers.

This patch adds an AllowOverrideAndFinal option defaulting to 0 - thus preserving current behavior - that when enabled allows both `override` and `final` to co-exist, while still fixing all other issues.

The patch includes a test file verifying all combinations of virtual/override/final, and mentions the new option in the release notes.

[clang-tidy] Fix readability-redundant-string-init for c++17/c++2a

Summary:
`readability-redundant-string-init` was one of several clang-tidy checks documented as failing for C++17. (The failure mode in C++17 is that it changes `std::string Name = ""`; to `std::string Name = Name;`, which actually compiles but crashes at run-time.)

Analyzing the AST with `clang -Xclang -ast-dump` showed that the outer `CXXConstructExprs` that previously held the correct SourceRange were being elided in C++17/2a, but the containing `VarDecl` expressions still had all the relevant information. So this patch changes the fix to get its source ranges from `VarDecl`.

It adds one test `std::string g = "u", h = "", i = "uuu", j = "", k;` to confirm proper warnings and fixit replacements in a single `DeclStmt` where some strings require replacement and others don't. The readability-redundant-string-init.cpp and readability-redundant-string-init-msvc.cpp tests now pass for C++11/14/17/2a.

[clang-tidy] add OverrideMacro to modernize-use-override check

Summary:
The usefulness of **modernize-use-override** can be reduced if you have to live in an environment where you support multiple compilers, some of which sadly are not yet fully C++11 compliant

some codebases have to use override as a macro OVERRIDE e.g.

```
// GCC 4.7 supports explicit virtual overrides when C++11 support is enabled.
```

This allows code to be compiled with C++11 compliant compilers and get warnings and errors that clang, MSVC,gcc can give, while still allowing other legacy pre C++11 compilers to compile the code. This can be an important step towards modernizing C++ code whilst living in a legacy codebase.

When it comes to clang tidy, the use of the **modernize-use-override** is one of the most useful checks, but the messages reported are inaccurate for that codebase if the standard approach is to use the macros OVERRIDE and/or FINAL.

When combined with fix-its that introduce the C++11 override keyword, they become fatal, resulting in the modernize-use-override check being turned off to prevent the introduction of such errors.

This revision, allows the possibility for the replacement **override **to be a macro instead, Allowing the clang-tidy check to be run on both pre and post C++11 code, and allowing fix-its to be applied.

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.

struct B : A

// Generated Fixit: void il(IntPair p = override {1, (2 + 3)}) {};
// Should be: void il(IntPair p = {1, (2 + 3)}) override {};

[clang-tidy] fix a couple of modernize-use-override bugs

Fix for __declspec attributes and const=0 without space

This patch is to address 2 problems I found with Clang-tidy:modernize-use-override.

1: missing spaces on pure function decls.

Orig:
void pure() const=0
Problem:
void pure() constoverride =0
Fixed:
void pure() const override =0

2: This is ms-extension specific, but possibly applies to other attribute types. The override is placed before the attribute which doesn’t work well with declspec as this attribute can be inherited or placed before the method identifier.

Orig:
class __declspec(dllexport) X : public Y

{
void p();
};
Problem:
class override __declspec(dllexport) class X : public Y

{
void p();
};
Fixed:
class __declspec(dllexport) class X : public Y

{
void p() override;
};
