George Karpenkov a763fdfadd [ASTMatcher] Extend hasAnyArgument to ObjCMessageExpr
Currently hasArgument works with both ObjC messages and function calls,
but not hasAnyArgument.
This patch fixes that discrepancy, as it's often more convenient to use
hasAnyArgument.

On a more general note, it would be great to have a common superclass
for objc-call and function call, and a matcher matching that, but that's
probably a job for another commit.

Francois Ferrand 2a9ea781f3 [clang-format] Add SpaceBeforeColon option
Summary:
When disabled, this option allows removing the space before colon,
making it act more like the semi-colon. When enabled (default), the
current behavior is not affected.

This mostly affects C++11 loop, initializer list, inheritance list and
container literals:

  class Foo: Bar {}
  Foo::Foo(): a(a) {}
  for (auto i: myList) {}
  f({a: 1, b: 2, c: 3});

Akira Hatanaka 7275da0f2e [ObjC] Allow declaring __strong pointer fields in structs in Objective-C
ARC mode.

Declaring __strong pointer fields in structs was not allowed in
Objective-C ARC until now because that would make the struct non-trivial
to default-initialize, copy/move, and destroy, which is not something C
was designed to do. This patch lifts that restriction.

Special functions for non-trivial C structs are synthesized that are
needed to default-initialize, copy/move, and destroy the structs and
manage the ownership of the objects the __strong pointer fields point
to. Non-trivial structs passed to functions are destructed in the callee
function.

Roman Lebedev 6017bf4f31 [Tooling] [0/1] Refactor FrontendActionFactory::create() to return std::unique_ptr<>
Summary:
Noticed during review of D41102.

I'm not sure whether there are any principal reasons why it returns raw owning pointer,
or it is just a old code that was not updated post-C++11.

I'm not too sure what testing i should do, because `check-all` is not error clean here for some reason,
but it does not //appear// asif those failures are related to these changes.

This is clang part.
Clang-tools-extra part is D43780.

Eric Fiselier 123c749ee9 [Driver] Add option to manually control discarding value names in LLVM IR.
Summary:
Currently, assertion-disabled Clang builds emit value names when generating LLVM IR. This is controlled by the `NDEBUG` macro, and is not easily overridable. In order to get IR output containing names from a release build of Clang, the user must manually construct the CC1 invocation w/o the `-discard-value-names` option. This is less than ideal.

For example, Godbolt uses a release build of Clang, and so when asked to emit LLVM IR the result lacks names, making it harder to read. Manually invoking CC1 on Compiler Explorer is not feasible.

This patch adds the driver options `-fdiscard-value-names` and `-fno-discard-value-names` which allow the user to override the default behavior. If neither is specified, the old behavior remains.

Saleem Abdulrasool fd4db5331e Support `#pragma comment(lib, "name")` in the frontend for ELF
This adds the frontend support required to support the use of the
comment pragma to enable auto linking on ELFish targets. This is a
generic ELF extension supported by LLVM. We need to change the handling
for the "dependentlib" in order to accommodate the previously discussed
encoding for the dependent library descriptor. Without the custom
handling of the PCK_Lib directive, the -l prefixed option would be
encoded into the resulting object (which is treated as a frontend
error).

Summary:

I believe these used to be links, for which single backticks would
have been appropriate, but since they were un-link-ified in
https://reviews.llvm.org/rL275560, I believe monospace is now more
appropriate, and so two backticks are needed.

Test Plan:
Build the `docs-clang-html` target and confirm the options are rendered
using monospace font.

Eric Fiselier 1af6c114cc Add `__reference_binds_to_temporary` trait for checking safe reference initialization.
Summary:
The STL types `std::pair` and `std::tuple` can both store reference types. However their constructors cannot adequately check if the initialization of reference types is safe.  For example:

```
std::tuple<std::tuple<int> const&> t = 42;
// The stored reference is already dangling.
```

Libc++ has a best effort attempts in tuple to diagnose this, but they're not able to handle all valid cases (If I'm not mistaken). For example initialization of a reference from the result of a class's conversion operator.  Libc++ would benefit from having a builtin traits which can provide a much better implementation.

This patch introduce the `__reference_binds_to_temporary(T, U)` trait  that determines whether a reference of type `T` bound to an expression of type `U` would bind to a materialized temporary object.

Note that the trait simply returns false if `T` is not a reference type instead of reporting it as an error.

```
static_assert(__is_constructible(int const&, long));
static_assert(__reference_binds_to_temporary(int const&, long));
```
