238a6b7f09 [libomptarget] Remove stale omp handle
This was never used in the upstream compiler and was responsible
for some problems with reductions in the clang-ykt fork.

b305d26b57 [OpenMP] libomptarget: move debugging dumps under control of env var LIBOMPTARGET_DEBUG
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.

695c69316b Only use libdl when it is available
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.

1546d31924 [OpenMP] Changes in the plugin interface
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.

a620a0745f [libomptarget] Align test code with runtime/
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.

49739f0e32 [libomptarget] Fix Debug build with glibc < 2.18
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:
