The addition of the helper is split out from https://reviews.llvm.org/D69543
as suggested by Kadir. I also updated the existing uses to use the new API.
Summary:
This is mostly mechanical, with a few exceptions:
- getDeducedType moved into AST.h where it belongs. It now takes
ASTContext instead of ParsedAST, and avoids using the preprocessor.
- hover now uses SelectionTree directly rather than via
getDeclAtPosition helper
- hover on 'auto' used to find the decl that contained the 'auto' and
use that to set Kind and documentation for the hover result.
Now we use targetDecl() to find the decl matching the deduced type instead.
This changes tests, e.g. 'variable' -> class for auto on lambdas.
I think this is better, but the motivation was to avoid depending on
the internals of DeducedTypeVisitor. This functionality is removed
from the visitor.

This is shorter and usually the extra info is noise.
There are cases where the params become type-parameter-0-0 that are hard to fix.
This affects a few features:
- 'name' field in structured hover API (not exposed yet)
- 'name' field in locateSymbolAt (not exposed in LSP)
- 'document/symbol' - the symbol is hierarchically nested in the class
template, or written as foo<t>::foo when defined out-of-line.
Added a test case for hover from https://github.com/clangd/clangd/issues/76.
This patch fixes one field, but no fewer than four others are wrong!

Add a tweak for clangd to replace an auto keyword to the deduced type.
This way a user can declare something with auto and then have the
IDE/clangd replace auto with whatever type clangd thinks it is. In case
of long/complext types this makes is reduces writing effort for the
user.
The functionality is similar to the hover over the auto keyword.

/// auto x = Something();
/// ^^^^
/// After:
/// MyClass x = Something();
/// ^^^^^^^

Summary:
LSP now reflects the declaration/definition distinction.
Language server changes:
- textDocument/definition now returns a definition if one is found, otherwise
the declaration. It no longer returns declaration + definition if they are
distinct.
- textDocument/declaration returns the best declaration we can find.
- For macros, the active macro definition is returned for both methods.
- For include directive, the top of the target file is returned for both.
There doesn't appear to be a discovery mechanism (we can't return everything to
clients that only know about definition), so this changes existing behavior.
In practice, it should greatly reduce the fraction of the time we need to show
the user a menu of options.
C++ API changes:
- findDefinitions is replaced by locateSymbolAt, which returns a
vector<LocatedSymbol> - one for each symbol under the cursor.
- this contains the preferred declaration, the definition (if found), and
the symbol name
This API enables some potentially-neat extensions, like swapping between decl
and def, and exposing the symbol name to the UI in the case of multiple symbols.

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

Standardize on the most common namespace setup in our *.cpp files:
using namespace llvm;
namespace clang {
namespace clangd {
void foo(StringRef) { ... }
And remove redundant llvm:: qualifiers. (Except for cases like
make_unique where this causes problems with std:: and ADL).
This choice is pretty arbitrary, but some broad consistency is nice.
This is going to conflict with everything. Sorry :-/
Squash the other configurations:
A)
using namespace llvm;
using namespace clang;
using namespace clangd;
void clangd::foo(StringRef);
This is in some of the older files. (It prevents accidentally defining a
new function instead of one in the header file, for what that's worth).
B)
namespace clang {
namespace clangd {
void foo(llvm::StringRef) { ... }
This is fine, but in practice the using directive often gets added over time.
C)
namespace clang {
namespace clangd {
using namespace llvm; // inside the namespace
This was pretty common, but is a bit misleading: name lookup preferrs
clang::clangd::foo > clang::foo > llvm:: foo (no matter where the using
directive is).

In getAbsoluteFilePath, we try to obtain the realpath of the FileEntry
by calling tryGetRealPathName. However, this can fail and return an
empty string. It may be bug a bug in clang, but in any case we should
fall back to computing it ourselves if it happens.
I changed getAbsoluteFilePath so that if tryGetRealPathName succeeds, we
return right away (a real path is always absolute). Otherwise, we try
to build an absolute path, as we did before, but we also call
VFS->getRealPath to make sure to get the canonical path (e.g. without
any ".." in it).

log() is split into four functions:

All logging functions use formatv-style format strings now, e.g:
log("Could not resolve URI {0}: {1}", URI, Result.takeError());
Existing log sites have been split between elog/log/vlog by best guess.
This includes a workaround for passing Error to formatv that can be

Summary:
The Language Server Protocol unfortunately mandates that locations in files
be represented by line/column pairs, where the "column" is actually an index
into the UTF-16-encoded text of the line.
(This is because VSCode is written in JavaScript, which is UTF-16-native).
Internally clangd treats source files at UTF-8, the One True Encoding, and
generally deals with byte offsets (though there are exceptions).
Before this patch, conversions between offsets and LSP Position pretended
that Position.character was UTF-8 bytes, which is only true for ASCII lines.
Now we examine the text to convert correctly (but don't actually need to
transcode it, due to some nice details of the encodings).
The updated functions in SourceCode are the blessed way to interact with
the Position.character field, and anything else is likely to be wrong.
So I also updated the other accesses:
- CodeComplete needs a "clang-style" line/column, with column in utf-8 bytes.
This is now converted via Position -> offset -> clang line/column
(a new function is added to SourceCode.h for the second conversion).
- getBeginningOfIdentifier skipped backwards in UTF-16 space, which is will
behave badly when it splits a surrogate pair. Skipping backwards in UTF-8
coordinates gives the lexer a fighting chance of getting this right.
While here, I clarified(?) the logic comments, fixed a bug with identifiers
containing digits, simplified the signature slightly and added a test.
This seems likely to cause problems with editors that have the same bug, and
treat the protocol as if columns are UTF-8 bytes. But we can find and fix those.

For example, for a variable:
Declared in class Foo::Bar
int hello = 2

- markdown support (the client I use doesn't support it yet)
- range support (optional in the Hover response)

Relative paths could be returned in some cases, e.g. when relative
path is used in compilation arguments. This led to crash when trying
to convert the path to URI.

Summary:
Instead of passing Context explicitly around, we now have a thread-local
Context object `Context::current()` which is an implicit argument to
every function.
Most manipulation of this should use the WithContextValue helper, which
augments the current Context to add a single KV pair, and restores the
old context on destruction.
Advantages are:
- less boilerplate in functions that just propagate contexts
- reading most code doesn't require understanding context at all, and
using context as values in fewer places still
- fewer options to pass the "wrong" context when it changes within a
scope (e.g. when using Span)
- contexts pass through interfaces we can't modify, such as VFS
- propagating contexts across threads was slightly tricky (e.g.
copy vs move, no move-init in lambdas), and is now encapsulated in
the threadpool
Disadvantages are all the usual TLS stuff - hidden magic, and
potential for higher memory usage on threads that don't use the
context. (In practice, it's just one pointer)

Summary:
o Replace the existing clangd::URI with a wrapper of FileURI which also
carries a resolved file path.
o s/FileURI/URI/
o Get rid of the URI hack in vscode extension.

Summary:
For some cases, GoToDefinition will navigate to the forward class
declaration, we should always navigate to the class definition.

Going to add unit tests in the next patch. (Haha!) But seriously there's
some work to do first - need to extract the markers-in-source-code
parser from CodeComplete test and make it more flexible, to allow
annotated ranges etc.
