Summary:
Basic CUDA platform implementation and cmake infrastructure to control
whether it's used. A few important TODOs will be handled in later
patches:
* Log some error messages that can't easily be returned as Errors.
* Cache modules and kernels to prevent reloading them if someone tries to
reload a kernel that's already loaded.
* Tolerate shared memory arguments for kernel launches.

Summary:
Build configuration was adding $(llvm-config --cxxflags) to the
StreamExecutor CXXFLAGS, but this was causing "-O3" to be passed even
for debug builds, and was making debugging difficult.
The llvm-config call was originally introduced to handle the -fno-rtti
flag because an RTTI StreamExecutor could not link with a no-RTTI LLVM.
This patch converts to using LLVM_ENABLE_RTTI and only adding the
`-fno-rtti` flag if needed, not all the rest of the LLVM CXXFLAGS.
I have tested this with clang-4.0 and gcc-4.8 on Ubuntu. Some work will
probably have to be done to support MSVC.

Summary:
With these changes, we can put parallel-libs within llvm/projects and
build as normal.
This is kind of the minimal change I could figure out how to make while
still making us compatible with llvm's build system. Some things I'm
not thrilled about include:
* The creation of a CoreTests directory (the macros really seemed to
want this)
* Pulling SimpleHostPlatformDevice.h into CoreTests. It seems to me
this should live inside unittests/include, or maybe tests/include,
but I didn't want to make that change in this patch.
One important piece of work that remains to be done is to make
$ ninja check-streamexecutor
run all the tests. Right now the only way I've figured out to run the
tests is
$ ninja projects/parallel-libs/streamexecutor/unittests/StreamExecutorUnitTests
$ projects/parallel-libs/streamexecutor/unittests/CoreTests/CoreTests

applications linking against StreamExecutor.

The "install" build target will now copy the StreamExecutor library and
headers to the appropriate subdirectories of CMAKE_INSTALL_PREFIX.
llvm-svn: 280506
Summary:
Consolidate Executor::synchronousCopy* and Stream::thenCopy* methods into
Doxygen method groups and combine all their comments into one section.
Also a "doc" target to the build files to use Doxygen to build the
documentation.

Summary:
Add definitions for the KernelLoaderSpec and MultiKernelLoaderSpec
classes to StreamExecutor. Instances of these classes are generated by the
compiler in order to provide host code with a handle to device code.

Summary:
Error handling in StreamExecutor is based on llvm::Error and
llvm::Expected. This CL sets up the StreamExecutor wrapper classes in
the streamexecutor namespace.
All the other StreamExecutor code makes use of this error handling code,
so this is the first CL for checking in StreamExecutor.
