Summary:
This allows efficiently accessing all expansions (without iterating over each
token and searching), and also identifying tokens within a range that are
affected by the preprocessor (which is how clangd will use it).

Summary:
If there is no record in compile_commands.json, we try to find suitable record with `MatchTrie.findEquivalent()` call.
This is very expensive operation with a lot of `llvm::sys::fs::equivalent()` calls in some cases.
This patch disables file symlinks for performance reasons.
Example scenario without this patch:
- compile_commands.json generated at clangd build (contains ~3000 files).
- it tooks more than 1 second to get compile command for newly created file in the root folder of LLVM project.
- we wait for 1 second every time when clangd requests compile command for this file (at file change).

* as we are using them only for integer and floating literals they have
the same behavior
* FileRange::text is simpler to call and is within the context of
syntax trees
Summary:
Given an UserDefinedLiteral `1.2_w`:
Problem: Lexer generates one Token for the literal, but ClangAST
references two source locations
Fix: Ignore the operator and interpret it as the underlying literal.
e.g.: `1.2_w` token generates syntax node IntegerLiteral(1.2_w)

Summary:
How does RecursiveASTVisitor call the WalkUp callback for expressions?
* In pre-order traversal mode, RecursiveASTVisitor calls the WalkUp
callback from the default implementation of Traverse callbacks.
* In post-order traversal mode when we don't have a DataRecursionQueue,
RecursiveASTVisitor also calls the WalkUp callback from the default
implementation of Traverse callbacks.
* However, in post-order traversal mode when we have a DataRecursionQueue,
RecursiveASTVisitor calls the WalkUp callback from PostVisitStmt.
As a result, when the user overrides the Traverse callback, in pre-order
traversal mode they never get the corresponding WalkUp callback. However
in the post-order traversal mode the WalkUp callback is invoked or not
depending on whether the data recursion optimization could be applied.
I had to adjust the implementation of TraverseCXXForRangeStmt in the
syntax tree builder to call the WalkUp method directly, as it was
relying on this behavior. There is an existing test for this
functionality and it prompted me to make this extra fix.
In addition, I had to fix the default implementation implementation of
RecursiveASTVisitor::TraverseSynOrSemInitListExpr to call WalkUpFrom in
the same manner as the implementation generated by the DEF_TRAVERSE_STMT
macro. Without this fix, the InitListExprIsPostOrderNoQueueVisitedTwice
test was failing because WalkUpFromInitListExpr was never called.

This change adds a Metadata field to ASTEdit, Edit, and AtomicChange so that
edits can have associated metadata and that metadata can be constructed with
Transformer-based RewriteRules. Metadata is ignored when applying edits to
source, but other consumers of AtomicChange can use this metadata to direct how
they want to consume each edit.

Summary:
As discussed previously when landing patch for OpenMP in Flang, the idea is
to share common part of the OpenMP declaration between the different Frontend.
While doing this it was thought that moving to tablegen instead of Macros will also
give a cleaner and more powerful way of generating these declaration.
This first part of a future series of patches is setting up the base .td file for
DirectiveLanguage as well as the OpenMP version of it. The base file is meant to
be used by other directive language such as OpenACC.
In this first patch, the Directive and Clause enums are generated with tablegen
instead of the macros on OMPConstants.h. The next pacth will extend this
to other enum and move the Flang frontend to use it.

Summary:
Currently, `cat` validates range selections before extracting the corresponding
source text. However, this means that any range inside a macro is rejected as an
error. This patch changes the implementation to first try to map the range to
something reasonable. This makes the behavior consistent with handling of ranges
used for selecting portions of the source to edit.
Also updates a clang-tidy lit-test for one of the checks which was affected by
this change.

This patch adds a parser for a `RangeSelector` written as a string. The format
is closely based on the way one would right the selector in C++. This should
enable use of `RangeSelector`s from tools like clang-query and web UIs.
When targetting CodeView, the goal is to store argv0 & cc1 cmd-line in the emitted .OBJ, in order to allow a reproducer from the .OBJ alone.

Summary:
Currently, all changes returned by a single application of a rule must fit in
one atomic change and therefore must apply to one file. However, there are
patterns in which a single rule will want to modify multiple files; for example,
a header and implementation to change a declaration and its definition. This
patch relaxes Transformer, libTooling's interpreter of RewriteRules, to support
multiple changes.

Summary:
This revision simplifies the representation of edits in rewrite rules. The
simplified form is more general, allowing the user more flexibility in building
custom edit specifications.
The changes extend the API, without changing the signature of existing
functions. So this only risks breaking users that directly accessed the
`RewriteRule` struct.
