Ben Hamilton f94c10d91a [clang-tidy objc-property-declaration] New option IncludeDefaultAcronyms
Summary:
The existing option objc-property-declaration.Acronyms
replaces the built-in set of acronyms.

While this behavior is OK for clients that don't want the default
behavior, many clients may just want to add their own custom acronyms
to the default list.

This revision introduces a new option,
objc-property-declaration.IncludeDefaultAcronyms, which controls
whether the acronyms in objc-property-declaration.Acronyms are
appended to the default list (the default behavior) or whether they
replace.

I also updated the documentation.

Haojian Wu 0e9a8a5f6f [clang-tidy] Don't generate fix for argument constructed from std::initializer_list.
Summary:
A follow-up fix of rL311652.

The previous `vector` in our test is different with `std::vector`, so
The check still generates fixes for std::vector (`auto p =
std::unique_ptr<Foo>(new Foo({1,2,3}))`) in real world, the patch makes the
vector behavior in test align with std::vector (both AST nodes are the same now).

Jonas Toth f22f3489d7 [clang-tidy] implement check for goto
The usage of `goto` is discourage in C++ since forever. This check implements
a warning for every `goto`. Even though there are (rare) valid use cases for
`goto`, better high level constructs should be used.

`goto` is used sometimes in C programs to free resources at the end of 
functions in the case of errors. This pattern is better implemented with
RAII in C++.

Ben Hamilton 490811ec3f [clang-tidy] Function-scoped static variables should not trigger google-objc-global-variable-declaration
Summary:
google-objc-global-variable-declaration currently triggers on
valid code like:

  - (void)foo {
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{ /* ... */ });
  }

The Google Objective-C style guide says:

http://google.github.io/styleguide/objcguide.html#common-variable-names

> File scope or global variables (as opposed to constants) declared
> outside the scope of a method or function should be rare, and should
> have the prefix g.

which is meant to insinuate that static variables inside a method or
function don't need a special name.

Shoaib Meenai d806af3499 [CMake] Use PRIVATE in target_link_libraries for executables
We currently use target_link_libraries without an explicit scope
specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables.
Dependencies added in this way apply to both the target and its
dependencies, i.e. they become part of the executable's link interface
and are transitive.

Transitive dependencies generally don't make sense for executables,
since you wouldn't normally be linking against an executable. This also
causes issues for generating install export files when using
LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM
library dependencies, which are currently added as interface
dependencies. If clang is in the distribution components but the LLVM
libraries it depends on aren't (which is a perfectly legitimate use case
if the LLVM libraries are being built static and there are therefore no
run-time dependencies on them), CMake will complain about the LLVM
libraries not being in export set when attempting to generate the
install export file for clang. This is reasonable behavior on CMake's
part, and the right thing is for LLVM's build system to explicitly use
PRIVATE dependencies for executables.

Unfortunately, CMake doesn't allow you to mix and match the keyword and
non-keyword target_link_libraries signatures for a single target; i.e.,
if a single call to target_link_libraries for a particular target uses
one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must
also be updated to use those keywords. This means we must do this change
in a single shot. I also fully expect to have missed some instances; I
tested by enabling all the projects in the monorepo (except dragonegg),
and configuring both with and without shared libraries, on both Darwin
and Linux, but I'm planning to rely on the buildbots for other
configurations (since it should be pretty easy to fix those).

Even after this change, we still have a lot of target_link_libraries
calls that don't specify a scope keyword, mostly for shared libraries.
I'm thinking about addressing those in a follow-up, but that's a
separate change IMO.
