This allows removing the clangAST dependency from libclangToolingCore and
therefore allows clang-format to be built without depending on clangAST.
Before 1166 files had to be compiled for clang-format, now only 796.

Saves only 36 includes of ASTContext.h and related headers.
There are two deps on ASTContext.h:
- C++ method overrides iterator types (TinyPtrVector)
- getting LangOptions
For #1, duplicate the iterator type, which is
TinyPtrVector<>::const_iterator.
For #2, add an out-of-line accessor to get the language options. Getting
the ASTContext from a Decl is already an out of line method that loops
over the parent DeclContexts, so if it is ever performance critical, the
proper fix is to pass the context (or LangOpts) into the predicate in
question.
Other changes are just header fixups.
Summary: Instead of dropping all the ranges associated with a Diagnostic when
converting them to a ClangTidy error, instead attach them to the ClangTidyError,
so they can be consumed by other APIs.

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.
Update the callers of FileManager::getFile and FileManager::getDirectory to handle the new llvm::ErrorOr-returning methods.

Summary:
Motivation/Context: in the code review system integrating with clang-tidy,
clang-tidy doesn't provide a human-readable description of the fix. Usually
developers have to preview a code diff (before vs after apply the fix) to
understand what the fix does before applying a fix.
This patch proposes that each clang-tidy check provides a short and
actional fix description that can be shown in the UI, so that users can know
what the fix does without previewing diff.
This patch extends clang-tidy framework to support fix descriptions (will add implementations for
existing checks in the future). Fix descriptions and fixes are emitted via diagnostic::Note (rather than
attaching the main warning diagnostic).
Before this patch:
```
void MyCheck::check(...) {
...
diag(loc, "my check warning") << FixtItHint::CreateReplacement(...);
}
```
After:
```
void MyCheck::check(...) {
...
diag(loc, "my check warning"); // Emit a check warning
diag(loc, "fix description", DiagnosticIDs::Note) << FixtItHint::CreateReplacement(...); // Emit a diagnostic note and a fix
}
```

Summary:
For example, a renamed type in a header file can conflict with declaration in
a random file that includes the header, but we should not consider the decl ambiguous if
it's not visible at the rename location. This improves consistency of generated replacements
when header file is included in different TUs.

Summary:
Previously, when the renamed spelling is ambiguous, we simply use the
full-qualfied name (with leading "::"). This patch makes it try adding
additional specifiers one at a time until name is no longer ambiguous,
which allows us to find better disambuguated spelling.

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.

These offsets are useless (and even harmful in certain cases) in exported

This patch moves the virtual file system form clang to llvm so it can be
used by more projects.
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.

Summary:
The new error information contains the type of error (e.g. overlap or bad file path)
and the replacement(s) that is causing the error. This enables us to resolve some errors.
For example, for insertion at the same location conflict, we need to know the
existing replacement which conflicts with the new replacement in order to calculate
the new position to be insert before/after the existing replacement (for merging).

Summary:
Now two replacements are considered order-independent if applying them in
either order produces the same result. These include (but not restricted
to) replacements that:
- don't overlap (being directly adjacent is fine) and
- are overlapping deletions.
- are insertions at the same offset and applying them in either order
has the same effect, i.e. X + Y = Y + X if one inserts text X and the
other inserts text Y.

Summary:
No behavioral change intended. The change makes iterating the replacements set more intuitive in Replacements class implementation. Previously, insertion is ordered before an deletion/replacement with the same offset, which is counter-intuitive for implementation, especially for a followup patch to support adding insertions around replacements.
With the current ordering, we only need to make `applyAllReplacements` iterate the replacements set reversely when applying them so that deletion/replacement is still applied before insertion with the same offset.

Summary:
Extend `tooling::Replacements::add()` to support adding order-independent replacements.
Two replacements are considered order-independent if one of the following conditions is true:
- They do not overlap. (This is already supported.)
- One replacement is insertion, and the other is a replacement with
length > 0, and the insertion is adjecent to but not contained in the
other replacement. In this case, the replacement should always change
the original code instead of the inserted text.
