7d2aecbc76 Add XRay flags to Clang. We implement two flags to control the XRay behaviour:
-fxray-instrument: enables XRay annotation of IR
-fxray-instruction-threshold: configures the threshold for function size (looking at IR instructions), and allow LLVM to decide whether to add the nop sleds later on in the process.

Also implements the related xray_always_instrument and xray_never_instrument function attributes.

50aece03cb [analyzer] Implement a methond to discover origin region of a symbol.
This encourages checkers to make logical decisions depending on
value of which region was the symbol under consideration
introduced to denote.

A similar technique is already used in a couple of checkers;
they were modified to call the new method.

2404b17192 [OpenMP] Initial implementation of parse+sema for clause use_device_ptr of 'target data'
http://reviews.llvm.org/D21904

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):
https://github.com/clang-omp/OffloadingDesign

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

4d85003964 [OpenCL] Improved diagnostics of OpenCL types.
- 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.

58fab355e2 [clang-cl] Add support for /Zd
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.

c813c8113d [OpenCL] Fix access qualifiers handling for typedefs
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

cad622742e [analyzer] Add rudimentary handling of AtomicExpr.
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.

Summary:
Currently our handling of CUDA architectures is scattered all around

A key advantage of this centralization is that you can now write a C++
switch on e.g. CudaArch and get a compile error if you don't handle one
of the enum values.

db7a31cce7 [OpenCL] An implementation of device side enqueue (DSE) from OpenCL v2.0 s6.13.17.
- Added new Builtins: enqueue_kernel, get_kernel_work_group_size
and get_kernel_preferred_work_group_size_multiple.

These Builtins use custom check to diagnose parameters of the passed Blocks
i. e. variable number of 'local void*' type params, and check different
overloads specified in Table 6.31 of OpenCL v2.0.

- IR is generated as an internal library call for each OpenCL Builtin,
reusing ObjC Block implementation.
