Joseph Huber da8bec47ab [OpenMP] Add Location Fields to Libomptarget Runtime for Debugging
Summary:
Add support for passing source locations to libomptarget runtime functions using the ident_t struct present in the rest of the libomp API. This will allow the runtime system to give much more insightful error messages and debugging values.

Joseph Huber 97e55cfef5 [OpenMP] Add Passing in Original Declaration Names To Mapper API
Summary:
This patch adds support for passing in the original delcaration name in the source file to the libomptarget runtime. This will allow the runtime to provide more intelligent debugging messages. This patch takes the original expression parsed from the OpenMP map / update clause and provides a textual representation if it was explicitly mapped, otherwise it takes the name of the variable declaration as a fallback. The information in passed to the runtime in a global array of strings that matches the existing ident_t source location strings using ";name;filename;column;row;;"

Alexey Bataev 5292187a2d [OPENMP]Fix PR48076: mapping of data member pointer.
If the data member pointer is mapped, the compiler tries to optimize the
mapping of such data by discarding explicit mapping flags and trying to
emit combined data instead. In some cases, this optimization is not
quite correctly implemented and it leads to a program crash at the
runtime. Instead, if the data member is mapped, just emit it as is and
do not emit combined mapping flags for it.

Joseph Huber 1a4fb2edcb [OpenMP] Replace Clang's OpenMP RTL Definitions with OMPKinds.def
Summary: This changes Clang's generation of OpenMP runtime functions to use the types and functions defined in OpenMPKinds and OpenMPConstants. New OpenMP runtime function information should now be added to OMPKinds.def. This patch also changed the definitions of __kmpc_push_num_teams and __kmpc_copyprivate to match those found in the runtime.

Alexey Bataev c09c0651a4 [OPENMP]Fix PR43772: No warning in non-combined target regions.
Need to analyze inner target regions in case of implicit mapping of the
data members when target region is created in one of the class member
functions.

Alexey Bataev ec7946ea2d [OPENMP]Call __kmpc_push_tripcount in task context.
Runtime function __kmpc_push_tripcount better to call inside of the task
context for target regions. Otherwise, the libomptarget is unable to
link the provided tripcount value for nowait target regions and
completely looses this information.

Alexey Bataev 7bb3353f6a [OPENMP]Add call to __kmpc_push_target_tripcount() function.
Each we create the target regions with the teams distribute inner
region, we can better estimate number of the teams required to execute
the target region. Function __kmpc_push_target_tripcount() is used for
purpose, which accepts device_id and the number of the iterations,
performed by the associated loop.
