Summary: The alpha checkers can already be enabled using the clang driver, this allows them to be enabled using the clang-tidy as well. This can make it easier to test the alpha checkers with projects which already support the compile_commands.json. It will also allow more people to give feedback and patches about the alpha checkers since they can run it as part of clang tidy checks.

Previous implementation used to extract brief text from doxygen comments.
Brief text parsing slows down completion and is not suited for
non-doxygen comments.
This commit switches to providing comments that mimic the ones
originally written in the source code, doing minimal reindenting and
removing the comments markers to make the output more user-friendly.
It means we lose support for doxygen-specific features, e.g. extracting
brief text, but provide useful results for non-doxygen comments.
Switching the doxygen support back is an option, but I suggest to see
whether the current approach gives more useful results.

Summary:
Code completion scoring was embedded in CodeComplete.cpp, which is bad:
- awkward to test. The mechanisms (extracting info from index/sema) can be
unit-tested well, the policy (scoring) should be quantitatively measured.
Neither was easily possible, and debugging was hard.
The intermediate signal struct makes this easier.
- hard to reuse. This is a bug in workspaceSymbols: it just presents the
results in the index order, which is not sorted in practice, it needs to rank
them!
Also, index implementations care about scoring (both query-dependent and
independent) in order to truncate result lists appropriately.
The main yak shaved here is the build() function that had 3 variants across
unit tests is unified in TestTU.h (rather than adding a 4th variant).

Summary:
As discussed in D45931, currently, profiling output of clang-tidy is somewhat not great.
It outputs one profile at the end of the execution, and that profile contains the data
from the last TU that was processed. So if the tool run on multiple TU's, the data is
not accumulated, it is simply discarded.
It would be nice to improve this.
This differential is the first step - make this profiling info per-TU,
and output it after the tool has finished processing each TU.
In particular, when `ClangTidyASTConsumer` destructor runs.
Next step will be to add a CSV (JSON?) printer to store said profiles under user-specified directory prefix.

llvm-svn: 331189
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.

llvm-svn: 330772
Summary:
This is a basic implementation of the "workspace/symbol" request which is
used to find symbols by a string query. Since this is similar to code completion
in terms of result, this implementation reuses the "fuzzyFind" in order to get
matches. For now, the scoring algorithm is the same as code completion and
improvements could be done in the future.
The index model doesn't contain quite enough symbols for this to cover
common symbols like methods, enum class enumerators, functions in unamed
namespaces, etc. The index model will be augmented separately to achieve this.

But it's not set for clang-tidy, so for ex. DCHECK in Chromium is not considered as [[no-return]], and a lot of false-positive warnings about nullptr dereferenced are emitted.
This patch fixes the issue by explicitly added macro definition.

Summary:
This patch adds support for incremental document syncing, as described
in the LSP spec. The protocol specifies ranges in terms of Position (a
line and a character), and our drafts are stored as plain strings. So I
see two things that may not be super efficient for very large files:
- Converting a Position to an offset (the positionToOffset function)
requires searching for end of lines until we reach the desired line.
- When we update a range, we construct a new string, which implies
copying the whole document.
However, for the typical size of a C++ document and the frequency of
update (at which a user types), it may not be an issue. This patch aims
at getting the basic feature in, and we can always improve it later if
we find it's too slow.

When no inputs given, the tools should not only produce the help message, but
also return a non-zero exit code. Fixed tests accordingly.

Adding the config initialization to clang-tools-extra so that tests that
use REQUIRES, UNSUPPORTED, and XFAIL based on platform or target triple
work properly.

After changes to lit.site.cfg.in, the test is now running (and failing)
on windows, so temporarily marking it unsupported. See PR36855 for more
details.
