This patch updates the implementation of the ompt_frame_t, ompt_wait_id_t
and ompt_state_t. The final version of the OpenMP 5.0 spec added the "t"
for these types.
Furthermore the structure for ompt_frame_t changed and allows to specify
that the reenter frame belongs to the runtime.

Clang 5 or higher adds an intermediate function call in certain cases when
compiling with debug flag. This revision updates the testcases to work
correctly.

Reasons for expected failures are mainly bugs when using lables in OpenMP regions
or missing support of some OpenMP features.
For some worksharing clauses, support to distinguish the kind of workshare was
added just recently.
If an issue was fixed in a minor release version of a compiler, we flag the
test as unsupported for this compiler version to avoid false positives.
Same for fixes that where backported to older compiler versions.

The code is tested to work with latest clang, GNU and Intel compiler. The implementation
is optimized for low overhead when no tool is attached shifting the cost to execution with
tool attached.
This patch does not implement OMPT for libomptarget.

Previous differencials D23305-D23310 changed task frame information management only for the kmp interface, but not for the whole gomp interface. This broke some testcases when building with gcc.
This patch fixes the broken task frame information for the gomp interface.

The exit address is set when execution of a task is started and should be reset as soon as the execution is finished.
Especially for the asm implementation of __kmp_invoke_microtask, resetting in this call would be painfull, so reset just after the invokation.
The testcase shows the effect of this patch:
Before, the implicit barriers at the end of an implicit task would see an exit address for the implicit task.
This barrier is a task scheduling point. Thus, any explicit task scheduled there would see an exit, but no reenter address for the implicit task.

The latest OMPT spec changed the semantic of a tasks reenter frame to be the application frame, that will be entered, when the runtime frame drops.
Before it was the last frame in the runtime. This doesn't work for some gcc execution pathes or even clang generated code for :
Since there is no runtime frame between the executed task and the encountering task.
The test case compares exit and reenter addresses against addresses captured in application code

OMPT tests can check for right frame information of tasks:
* parent_task_frame was directly printed as a pointer, but actually points to a struct ompt_frame {void*, void*}
* NULL is printed in the beginning of execution and loaded to FileChecker variable [[NULL]]
* implicit tasks now also print their frame information
* macro to print frame address from application
* print task info for barrier begin

For non-serialized parallel regions the master thread issued two callbacks:
The first one in kmp_gsupport.c and the second in __kmp_join_call. Therefore
only trigger the callback in kmp_gsupport.c for serialized parallel regions.

Some basic checks next to the implementation should futher lower the
possibility to introduce regressions. (Note that this would have catched
the ordering issue fixed in rL258866 and pointed to rL263940.)
The tests are implementation dependent in one point because they assume that
thread ids are assigned in ascending order. This is not defined by the standard
but currently ensured in libomp. We have to think about another way of ordering
the threads should this ever be subject to change...
Note that this isn't aiming at replacing the implementation independent
