This patch is similar to the implementation of 'private' clause: it adds a list of private pointers to be used within the target data region to store the device pointers returned by the runtime.
Please refer to the following document for a full description of what the runtime witll return in this case (page 10 and 11):

I am happy to answer any question related to the runtime interface to help reviewing this patch.

Summary:
Specifically, this patch adds testcases for all three calls to
EraseUnwantedCUDAMatches. The addr-of-overloaded-fn test I accidentally
neutered in r264207, which moved much of
CodeGenCUDA/function-overload.cu into SemaCUDA/function-overload.cu.
The coverage from overloaded-delete test is new.

You can overload a destructor in CUDA, and SemaOverload needs to be
tweaked not to crash when it sees an explicit call to an overloaded
destructor.

A BuiltinTemplateDecl has no underlying templated decl and as such they
cannot be relied upon for mangling. The ItaniumMangler had some bugs
here which lead to crashes.

We need to mark the appropriate bits in ThrowInfo and HandlerType so

Do not assign source regions located within system headers file ID's,
and do not construct counter mapping regions out of them.
This makes coverage reports less cluttered and less mysterious. E.g
using the "assert" macro doesn't cause assert.h to appear in reports,
and it no longer shows the "assertion failed" branch as an uncovered
region.
It also makes coverage mapping sections a bit smaller (e.g a 1%
reduction in a stage2 build of bin/llvm-as).

Summary:
Nested if statements can generate empty BBs whose terminator branches
unconditionally to its successor. These branches are not eliminated
to help generate better line number information in some cases, but there
is no reason to keep the empty blocks that result from nested ifs.

- Changes diagnostics for Blocks to be implicitly
const qualified OpenCL v2.0 s6.12.5.
- Added and unified diagnostics of some OpenCL special types:
blocks, images, samplers, pipes. These types are intended for use
with the OpenCL builtin functions only and, therefore, most regular
uses are not allowed including assignments, arithmetic operations,
pointer dereferencing, etc.

Original Commit Message
Driver: Stop linking to C++ when using sanitizers on Darwin
Sanitizers on Darwin are built as dynamic libraries, not static libraries.
Sanitizers will have their C++ dependency satisfied internally (LC_LOAD_DYLIB)
in the libclang_rt dylib. As long as the sanitizers stay dynamic and not static,
linking against C++ when enabling a sanitizer becomes over linkage.

MASM (ML.exe and ML64.exe) and older versions of MSVC (CL.exe) support a
flag called /Zd which is more-or-less -gline-tables-only.
It seems nicer to support this flag instead of exposing
-gline-tables-only.

Place the structure data into `cfstring`. This both isolates the structures to
permit coalescing in the future (by the linker) as well as ensures that it
doesnt get marked as read-only data. The structures themselves are not
read-only, only the string contents.

OpenCL s6.6: "Access qualifier must be used with image object arguments
of kernels and of user-defined functions [...] If no qualifier is
provided, read_only is assumed".
This does not define the behavior for image types used in typedef
declaration, but following the spec logic, we should allow access
qualifiers specification in typedefs, e.g.:
typedef write_only image1d_t img1d_wo;
Unlike cv-qualifiers, user cannot add access qualifier to a typedef
type, i.e. this is not allowed:
typedef image1d_t img1d; // note: previously declared 'read_only' here
void foo(write_only img1d im) {} // error: multiple access qualifier

This proposed patch adds crude handling of atomics to the static analyzer.
Rather than ignore AtomicExprs, as we now do, this patch causes the analyzer
to escape the arguments. This is imprecise -- and we should model the
expressions fully in the future -- but it is less wrong than ignoring their
effects altogether.

The analyzer does not model C++ temporary destructors completely and so
reports false alarms about leaks of memory allocated by the internals of
shared_ptr:
std::shared_ptr<int> p(new int(1));
p = nullptr; // 'Potential leak of memory pointed to by field __cntrl_'
This patch suppresses all diagnostics where the end of the path is inside
a method in std::shared_ptr.
It also reorganizes the tests for suppressions in the C++ standard library
to use a separate simulated header for library functions with bugs
that were deliberately inserted to test suppression. This will prevent
other tests from using these as models.

Before r266366, clang used to support constructs like:
typedef __attribute__((vector_size(8))) double float64x1_t;
typedef __attribute__((vector_size(16))) double float64x2_t;
float64x1_t vget_low_f64(float64x2_t __p0);
double y = 3.0 + vget_low_f64(v);
But it would reject:
double y = vget_low_f64(v) + 3.0;
It also always rejected assignments:
double y = vget_low_f64(v);
This patch: (a) revivies the behavior of `3.0 + vget_low_f64(v)` prior to
r266366, (b) add support for `vget_low_f64(v) + 3.0` and (c) add support for
assignments.
These vector semantics have never really been tied up but it seems
odd that we used to support some binop froms but do not support
assignment. If we did support scalar for the purposes of arithmetic, we
should probably be able to reinterpret as scalar for the purposes of
assignment too.
