Summary:
Adds Semantic Ranges capabilities to Clangd server.
Also adds tests for running it via clangd server.
This differs from the LSP spec as the spec needs this to be evaluated on multiple 'pos' and the expected output is an list of list of semantic ranges.
This is majorly for multi cursor and assuming this is a rare thing, we don't want to optimize make things complicated just for this.
This should be done in the LSP level by queueing one request per 'pos' in the input.

Summary:
- Functions to compute highlighting kinds for things are separated from
the ones that add highlighting tokens.
This keeps each of them more focused on what they're doing: getting
locations and figuring out the kind of the entity, correspondingly.
- Less special cases in visitor for various nodes.
This change is an NFC.

Summary:
For a given cursor position, it returns ranges that are interesting to the user.
Currently the semantic ranges correspond to the nodes of the syntax trees.

Summary:
The renamelib uses a tricky way to calculate the end location by relying
on decl name, this is incorrect for the overloaded operator (the name is
"operator++" instead of "++"), which will cause out-of-file offset.
We also disable renaming operator symbol, this case is tricky, and
renamelib doesnt handle it properly.

Summary:
This takes ~5% of time when running clangd unit tests.
To achieve this, move mapping of system includes out of CanonicalIncludes
and into a separate class

Summary:
We still attempt to highlight them as underlying types, but fallback to
the generic 'typedef' highlighting kind if the underlying type is too
complicated.

First patch for propogating multifile changes from tweak outputs to LSP
WorkspaceEdits.
Uses SM to convert tooling::Replacements to TextEdits.
Errors out if there are any inconsistencies between the draft version and the

Summary:
Template parameters were handled outside `addType`, this led to lack of highlightings for typedefs
to template types.
This was never desirable, we want to highlight our typedefs as their underlying type.
Note that typedefs to more complicated types, like pointers and references are still not highlighted.
Original patch by Johan Vikström.

Summary:
Instead of matching lists of highlightings, we annotate input code with
resulting highlightings and diff it against the expected annotated input.
In case of failures, this produces much nicer output in form of text-based
diffs.

This much better reflects what is (now) in this header.
Maybe a rename to ParsedTU would be an improvement, but that's a much
more invasive change and life is too short.
ClangdUnit is dead, long live ClangdUnitTests!
llvm-svn: 370862
Summary:
This is the first part of an effort to "unbundle" our libIndex use into separate
concerns (AST traversal, token<->node mapping, node<->decl mapping,
decl<->decl relationshipes).
Currently, clangd relies on libIndex to associate tokens, AST nodes, and decls.
This leads to rather convoluted implementations of e.g. hover and
extract-function, which are not naturally thought of as indexing applications.
The idea is that by decoupling different concerns, we make them easier
to use, test, and combine, and more efficient when only one part is needed.
There are some synergies between e.g. traversal and finding
relationships between decls, hopefully the benefits outweight these.

Summary: Structured bindings are in a BindingDecl. The decl the declRefExpr points to are the BindingDecls. So this adds an additional if statement in the addToken function to highlight them.

Summary: TokenBuffer does not collect macro expansions inside macro arguments which is needed for semantic higlighting. Therefore collects macro expansions in the main file in a PPCallback when building the ParsedAST instead.
