Under the term "subchecker", I mean checkers that do not have a checker class on
their own, like unix.MallocChecker to unix.DynamicMemoryModeling.
Since a checker object was required in order to retrieve checker options,
subcheckers couldn't possess options on their own.
This patch is also an excuse to change the argument order of getChecker*Option,
it always bothered me, now it resembles the actual command line argument
(checkername:option=value).

Summary:
clang-formatting wants to add spaces around items in square braces, e.g. [1, 2] -> [ 1, 2 ]. Based on a quick check [1], it seems like most cases are using the [1, 2] format, so make that the consistent one.
[1] in llvm `.td` files, the regex `\[[^ ]` (bracket followed by not-a-space) shows up ~400 times, but `\[\s[^ ]` (bracket followed by one space and one not-a-space) shows up ~40 times => ~90% uses this format.

Summary:
getLLVMStyle() sets the default style, but doesn't take the language as a parameter, so can't set default parameters when they differ from C++. This change adds LanguageKind as an input to getLLVMStyle so that we can start doing that.

Summary:
This allows ASTs to be merged when they contain ChooseExpr (the GNU
__builtin_choose_expr construction). This is needed, for example, for
cross-CTU analysis of C code that makes use of __builtin_choose_expr.
The node is already supported in the AST, but it didn't have a matcher
in ASTMatchers. So, this change adds the matcher and adds support to
ASTImporter.
This was originally reviewed and approved in
https://reviews.llvm.org/D58292 and submitted as r354832. It was
reverted in r354839 due to failures on the Windows CI builds.
This version fixes the test failures on Windows, which were caused by
differences in template expansion between versions of clang on different
OSes. The version of clang built with MSVC and running on Windows never
expands the template in the C++ test in ImportExpr.ImportChooseExpr in
clang/unittests/AST/ASTImporter.cpp, but the version on Linux does for
the empty arguments and -fms-compatibility.
So, this version of the patch drops the C++ test for
__builtin_choose_expr, since that version was written to catch
regressions of the logic for isConditionTrue() in the AST import code
for ChooseExpr, and those regressions are also caught by
ASTImporterOptionSpecificTestBase.ImportChooseExpr, which does work on
Windows.

Currently clang-format would always emit a replacement for a block of Java imports even if it is correctly formatted:
```
% cat /tmp/Aggregator.java
import X;
% clang-format /tmp/Aggregator.java

<?xml version='1.0'?>
<replacements xml:space='preserve' incomplete_format='false'>
<replacement offset='0' length='9'>import X;</replacement>
</replacements>
%
```
This change makes clang-format not emit replacements in this case. Note that
there is logic to not emit replacements in this case for C++.

Summary:
This patch unifies all those tests which check the correctness of the
redecl chains. Previously we had several structurally very similar test
cases for each language construct (class, function, variable, function
template, ...).
We still use value-parameterized tests for the different AST
compatibility switches (-fdelayed-template-parsing, -fms-compatibility).
Gtest makes it possible to have either value-parameterized or
type-parameterized fixtures. However, we cannot have both value- and
type-parameterized test fixtures. So we use a value-parameterized test
fixture in the gtest sense. We intend to mimic gtest's type-parameters
via the type template parameter. We manually instantiate the different
tests with the each types.
After this patch I am planning to put the "generic redecl chain" related
tests into their own separate test file (in another patch).

Summary:
During import of a global variable with external visibility the lookup
will find variables (with the same name) but with static visibility.
Clearly, we cannot put them into the same redecl chain. The same is
true in case of functions. In this fix we filter the lookup results and
consider only those which have the same visibility as the decl we
currently import.
We consider two decls in two anonymous namsepaces to have the same
visibility only if they are imported from the very same translation
unit.

Summary:
Currently, `UnwrappedLineParser` thinks an arrow token after
an ObjC method expression is a C++ lambda arrow, so it formats:
```
[foo bar]->baz
```
as:
```
[foo bar] -> baz
```
Because `UnwrappedLineParser` runs before `TokenAnnotator`, it can't
know if the arrow token is after an ObjC method expression or not.
This diff makes `TokenAnnotator` remove the TT_LambdaArrow on
the arrow token if it follows an ObjC method expression.
Test Plan: New test added. Ran test with:
% ninja FormatTests && ./tools/clang/unittests/Format/FormatTests
Confirmed test failed before diff and passed after diff.

Currently `TestImportBase` is derived from `ParameterizedTestsFixture`
which explicitly states that the gtest parameter can be only an
`ArgVector`. This is a limitation when we want to create tests which may
have different parameters.
E.g. we would like to create tests where we can combine different test
parameters. So, for example we'd like gtest to be able to provide
parameters of `<std::tuple<ArgVector, const char *>` instead of a simple
`ArgVector`.

Summary:
r347205 fixed a bug in FileManager: first calling
getFile(shouldOpen=false) and then getFile(shouldOpen=true) results in
the file not being open.
Unfortunately, some code was (inadvertently?) relying on this bug: when
building with a PCH, the file entries are obtained first by passing
shouldOpen=false, and then later shouldOpen=true, without any intention
of reading them. After r347205, they do get unneccesarily opened.
Aside from extra operations, this means they need to be closed. Normally
files are closed when their contents are read. As these files are never
read, they stay open until clang exits. On platforms with a low
open-files limit (e.g. Mac), this can lead to spurious file-not-found
errors when building large projects with PCH enabled, e.g.
https://bugs.chromium.org/p/chromium/issues/detail?id=924225
Fixing the callsites to pass shouldOpen=false when the file won't be
read is not quite trivial (that info isn't available at the direct
callsite), and passing shouldOpen=false is a performance regression (it
results in open+fstat pairs being replaced by stat+open).
So an ideal fix is going to be a little risky and we need some fix soon
(especially for the llvm 8 branch).
The problem addressed by r347205 is rare and has only been observed in
clangd. It was present in llvm-7, so we can live with it for now.
