They are a little bit of a special case in the mangling. They are always
mangled without taking into account their virtual-ness of the
destructor. They are also mangled to return void, unlike the actual
destructor.
This fixes PR31931.

such guides below explicit ones, and ensure that references to the class's
template parameters are not treated as forwarding references.
We make a few tweaks to the wording in the current standard:
1) The constructor parameter list is copied faithfully to the deduction guide,
without losing default arguments or a varargs ellipsis (which the standard
wording loses by omission).
2) If the class template declares no constructors, we add a T() -> T<...> guide
(which will only ever work if T has default arguments for all non-pack
template parameters).
3) If the class template declares nothing that looks like a copy or move
constructor, we add a T(T<...>) -> T<...> guide.
#2 and #3 follow from the "pretend we had a class type with these constructors"
philosophy for deduction guides.

This bypasses integer sanitization checks which are redundant on the expression since it's been checked by Sema. Fixes a clang codegen assertion on "void test() { new int[0+1]{0}; }" when building with -fsanitize=signed-integer-overflow.

This commit adds context sensitive code completion support for the C++11
keywords that currently don't have completion results.
The following keywords are supported by this patch:
alignas
constexpr
static_assert
noexcept (as a function/method qualifier)
thread_local
The following special identifiers are also supported:
final (as a method qualifier or class qualifier)
override

Summary:
Sema::CheckCompletedCoroutineBody was growing unwieldy with building all of the substatements. Also, constructors for CoroutineBodyStmt had way too many parameters.
Instead, CoroutineBodyStmt now defines CtorArgs structure with all of the required construction parameters.
CheckCompleteCoroutineBody delegates construction of individual substatements to short functions one per each substatement.
Also, added a drive-by fix of initializing CoroutinePromise to nullptr in ScopeInfo.h.
And addressed the FIXME that wanted to tail allocate extra room at the end of the CoroutineBodyStmt to hold parameter move expressions. (The comment was longer that the code that implemented tail allocation).

On Windows the filename might have an extension, namely
`.exe`, so the search will fail. Sorry, I don't have a
good way to test this as it seems to fail only in some
weird configurations. r284430 has the same modification

Use # as the comment leader for AArch64 auto-release elision marker.
This is to keep it in sync with the value used in swift. When building
libdispatch for Linux AArch64, the auto-release elision marker was
emitted. However, ELF uses # as the comment leader while MachO accepts
both ; and #. Use the common marker for it instead.

Certain ARC runtime functions have an ABI contract of being forwarding.
Annotate the functions with the appropriate `returned` attribute on the
arguments. This hoists some of the runtime ABI contract information
into the frontend rather than the backend transformations.
The test adjustments are to mark the returned function parameter as
such. The minor change to the IR output is due to the fact that the
returned reference of the object causes it to extend the lifetime of the
object by returning an autoreleased return value. The result is that
the explicit objc_autorelease call is no longer formed, as autorelease
elision is now possible on the return.

powerpc64 big-endian is not supported, but I believe that most logic can

Also add a function InvalidateInstructionCache to xray_util.h, which is
copied from llvm/Support/Memory.cpp. I'm not sure if I need to add a unittest,
and I don't know how.

Expose the half type (fp16) through libclang and the python bindings.
It seems CXType_LastBuiltin was not updated in b2ea6d9 ("Enable
support for __float128 in Clang", 2016-04-13), so update it now.
Add an Index test for OpenCL types; in the future we will add other
OpenCL types such as images to this test.
