Summary: The minimum compilers support all have alignas, and we don't use LLVM_ALIGNAS anywhere anymore. This also removes an MSVC diagnostic which, according to the comment above, isn't relevant anymore.

Introduce a new check to upgrade user code based on API changes in Googletest.
The check finds uses of old Googletest APIs with "case" in their name and replaces them with the new APIs named with "suite".

Sprinkled some #ifndef NDEBUG in Selection.cpp to make
it possible to build with NDEBUG defined.
The problem was introduced in rL366698 when using dlog
for some debug printouts. The dlog macro expands to
DEBUG_WITH_TYPE, which isn't using it's arguments in
optimized builds (when NDEBUG is defined).

Summary:
These aren't formally subexpressions in C++, in this case + is left-associative.
However informally +, *, etc are usually (mathematically) associative and users
consider these subexpressions.
We detect these and in simple cases support extracting the partial expression.
As well as builtin associative operators, we assume that overloads of them
are associative and support those too.

Summary:
Now that clang is going to be able to build the Linux kernel again on
x86, and we have gen_compile_commands.py upstream for generating
compile_commands.json, clang-tidy can be used on the Linux kernel
source.
To that end, this commit adds a new clang-tidy module to be used for
checks specific to Linux kernel source. The Linux kernel follows its own
style of C, and it will be useful to separate those checks into their
own module.
This also adds an initial check that makes sure that return values from
the kernel error functions like PTR_ERR and ERR_PTR are checked. It also
makes sure that any functions that directly return values from these
functions are checked.

This simplifies various workflows, particularly in debugging/development.
e.g. editors will tend to propagate flags, so you can run
`env CLANGD_FLAGS=-input-mirror-file=/tmp/mirror vim foo.cc` rather than
change the configuration in a persistent way.
(This also gives us a generic lever when we don't know how to customize
the flags in some particular LSP client).
While here, add a test for this and other startup logging, and fix a
couple of direct writes to errs() that should have been logs.

Summary:
Restricting the categories prevents extra unwanted options from creeping into
help (D60663), and removes a bunch of noise from --help-hidden.
While here, remove `static` from the opts in favor of an anon namespace, to

Summary:
Previously TranslationUnitDecl would never be selected.
This means root() is never null, and returns a reference.
commonAncestor() is in principle never null also, but returning TUDecl
here requires tweaks to be careful not to traverse it (this was already
possible when selecting multiple top-level decls, and there are associated bugs!)
Instead, never allow commonAncestor() to return TUDecl, return null instead.

Summary:
QualifiedTypeLoc isn't treated like a regular citizen by RecursiveASTVisitor.
This meant we weren't intercepting the traversal of its inner TypeLoc.
Most of the changes here are about exposing kind() so we can improve the
precision of our tests.
This should fix the issue raised in D65067.

Summary:
SelectionTree is a RecursiveASTVisitor which processes getSourceRange() for
every node. This is a lot of surface area with the AST, as getSourceRange()
is specialized for *many* node types.
And the resulting SelectionTree depends on the source ranges of many
visited nodes, and the order of traversal.
Put together, this means we really need a traversal log to debug when we
get an unexpected SelectionTree. I've built this ad-hoc a few times, now
it's time to check it in.

llvm-svn: 366545
Summary:
Changes persistance logic to store shards at the directory of closest
CDB. Previously we were storing all shards to directory of the CDB that
triggered indexing, it had its downsides.
For example, if you had two TUs coming from a different CDB but depending on the
same header foo.h, we will store the foo.h only for the first CDB, and it would
be missing for the second and we would never persist it since it was actually
present in the memory and persisted before.
This patch still stores only a single copy of a shard, but makes the directory a
function of the file name. So that the shard place will be unique even with
multiple CDBs accessing the file. This directory is determined as the first
directory containing a CDB in the file's parent directories, if no such
directory exists we make use of the home directory.
