We now have several options that apply for both libraries and they
shouldn't be documented in multiple files. When already merging
the two Build_With_CMake.txt documents, convert them to
reStructuredText which is used for all of LLVM's documentation.

This last of four patches adds a new file for the interface
functions that Clang uses during code generation. The only
change except simply moving the current code is renaming the
function CheckDeviceAndCtors() and using the correct type for
64bit device ids.

This third patch moves the implementation of the user-facing
OpenMP API functions into its own file. For now, the code is
only moved, no cleanups applied yet.

This is the second patch to split the current monolithic
implementation into separate files. Note that this change
doesn't cleanup the code yet.

This is the first of four patches to split the target agnostic
library into multiple (smaller) files. It only moves the code
to separate implementation files and does no cleanup (yet) except
removing unneeded headers.

Future patches will add (private) header files in src/ that should
not be visible to plugins, so move the "public" ones to a new
include/ directory. This is still internal in a sense that the
contained files won't be installed for the user.
Similarly, the target agnostic offloading library should be built
directly in src/. The parent directory is responsible for finding
dependencies and including all subdirectories.

Perform a nested CMake invocation to avoid writing our own parser
for compiler versions when we are not testing the in-tree compiler.
Use the extracted information to mark a test as unsupported that
hangs with Clang prior to version 4.0.1 and restrict tests for
libomptarget to Clang version 6.0.0 and later.

The code for the two OpenMP runtime libraries was very similar.
Move to common CMake file that is included and provides a simple
interface for adding testsuites. Also add a common check-openmp
target that runs all testsuites that have been registered.
Note that this renames all test options to the common OPENMP
namespace, for example OPENMP_TEST_C_COMPILER instead of
LIBOMP_TEST_COMPILER and so on.

These are needed by both libraries, so we can do that in a
common namespace and unify configuration parameters.
Also make sure that the user isn't requesting libomptarget
if the library cannot be built on the system. Issue an error
in that case.

As a first step, this allows us to generalize the detection of
standalone builds and make it fully compatible when building in
llvm/runtimes/ which automatically sets OPENMP_STANDLONE_BUILD.

We have just fixed the codegen of omp_is_initial_device() to reliably work
when offloading to the same device, see commit r316001. This fixes the
failing tests that were the reason why we disabled the library for 5.0.

This is the libomptarget-side patch which changes the __tgt_* API function signatures in preparation for the new map interface.
Changes are: Device IDs 32bits --> 64bits, Flags 32bits --> 64bits

In standalone build, plugins where previously built in their
subdirectory in plugins/ and tests couldn't find them.

Disable default debugging dumps for libomptarget and plugins and move dumps
under control of environment variable LIBOMPTARGET_DEBUG=<integer>. Dumps
are enabled when LIBOMPTARGET_DEBUG is set to a positive integer value.
Debugging dumps are available only in debug build; release build does not
support it.

Summary: On BSDs, there is no `libdl.so`, and functions like `dlopen`
are implemented in the main C library instead. Use the `CMAKE_DL_LIBS`
variable instead of hardcoding a dependency on the `dl` library.

This patch chagnes the plugin interface so that:
1) future plugins can take advantage of systems with shared CPU/device storage
2) instead of using base addresses, target regions are launched by providing target addresseds and base offsets explicitly.

Fixed bug due to which a parent struct was deallocated when one of the struct's pointers was being unmapped.

This change allows setting LIBOMPTARGET_LLVM_LIT_EXECUTABLE and
LIBOMPTARGET_FILECHECK_EXECUTABLE as full path. It also honors
OPENMP_LLVM_TOOLS_DIR which is meant as a common configuration
for both libomp and libomptarget.
Maybe this should be done in a common CMake module, but I'm no expert here.

glibc < 2.18 is C99 compliant and only provides the format macros in C++ if
__STDC_FORMAT_MACROS is defined. This change fixes the debug build for
GCC 4.8, GCC 6.2 and Clang 3.9.1 that were previously broken on my machine.
It shows no regression for libc++ >= 4.0.0 which has a fix since September:
