Preserve LD_LIBRARY_PATH when using the 'env' command

In many Linux environments (and similar), just-built applications won't run
correctly without making use of the current LD_LIBRARY_PATH environmental
variable in order to find dynamic libraries. Propagate it through the 'env'
command (hopefully this works on all platforms).

Cast vtable address points to i32 (...)** to enable more globalopt

We currently use i32 (...)** as the type of the vptr field in the LLVM
struct type. LLVM's GlobalOpt prefers any bitcasts to be on the side of
the data being stored rather than on the pointer being stored to.

CUDA host device code with two code paths

Summary:
Allow CUDA host device functions with two code paths using __CUDA_ARCH__
to differentiate between code path being compiled.

For example:
  __host__ __device__ void host_device_function(void) {
  #ifdef __CUDA_ARCH__
    device_only_function();
  #else
    host_only_function();
  #endif
  }

CMake: try to actually fix the regexes for setting HOST_LINK_VERSION this time (PR21268)

The regex should not accept an empty version number.

The previous attempt at r223106 failed, and the build was still erroring:

  CMake Error at tools/clang/CMakeLists.txt:269 (string):
    string sub-command REGEX, mode REPLACE regex "[^0-9]*([0-9.]*).*" matched
    an empty string.

Always emit kernel arg info for SPIR.

http://llvm.org/bugs/show_bug.cgi?id=21555

Currently, kernel argument metadata is omitted unless the
"-cl-kernel-arg-info" option is specified. But the SPIR 1.2 spec
requires that all metadata except kernel_arg_name should always be
emitted, and kernel_arg_name is only emitted when
"-cl-kernel-arg-info" is specified.
