Currently the affinity format string has initial value. When users set
the format via OMP_AFFINITY_FORMAT, it will overwrite the format string. However,
when copying the format, the tailing null is missing. As a result, if the user
format string is shorter than default value, the remaining part in the default
value still makes effort. This bug is not exposed because the test case doesn't
check the end of a string. It only checks whether given output "contains" the
check string.

As reported by @ronlieb, the test shows intermittent fails.
The test failed, if the dependent task was already finished, when the depending

This patch updates the expected results for the GOMP interface patches: D87267, D87269, and D87271.
The taskwait-depend test is changed to really use taskwait-depend and copied to an task_if0-depend test.
To pass the tests, the handling of the return address was fixed.

This change introduces the GOMP_taskwait_depend() function. It implements

Encapsulate GOMP task dependencies in separate class and introduce the
new mutexinoutset dependency type. This separate class allows
future GOMP task APIs easier access to the task dependency functionality

Summary:
The OpenMP loops are normalized and transformed into the loops from 0 to
max number of iterations. In some cases, original scheme may lead to
overflow during calculation of number of iterations. If it is unknown,
if we can end up with overflow or not (the bounds are not constant and
we cannot define if there is an overflow), cast original type to the
unsigned.

The OpenMP spec has the task-fulfill event for a call to omp_fulfill_event.
If the task did not yet finish execution, ompt_task_early_fulfill is used,
otherwise ompt_task_late_fulfill.
If a task does not complete, when the execution finishes (i.e., the task goes
in detached mode), ompt_task_detach instead of ompt_task_complete must be
used, when the next task is scheduled.
A test for both cases is included, which only work with clang-11+

D78566 introduced a `\bnot\b` lit substitution in OpenMP test suites.
However, that would corrupt a command like
`FileCheck -implicit-check-not` or any file name like `%t.not`. We
could use lookbehind/lookahead assertions to avoid such cases, but
this patch switches to `%not` (suggested during the D78566 review) as
a safer option.

Without this patch, the openmp project's test suites do not appear to
have support for negative tests. However, D78170 needs to add a test
that an expected runtime failure occurs.
This patch makes `not` visible in all of the openmp project's test
suites. In all but `libomptarget/test`, it should be possible for a
test author to insert `not` before a use of the lit substitution for
running a test program. In `libomptarget/test`, that substitution is
target-specific, and its value is `echo` when the target is not
available. In that case, inserting `not` before a lit substitution
would expect an `echo` fail, so this patch instead defines a separate
lit substitution for expected runtime fails.
