Sergio Afonso 66fca0674d [OpenMP] Fix num_iters in __kmpc_*_loop DeviceRTL functions (#133435) ...

This patch removes the addition of 1 to the number of iterations when
calling the following DeviceRTL functions:
- `__kmpc_distribute_for_static_loop*`
- `__kmpc_distribute_static_loop*`
- `__kmpc_for_static_loop*`

Calls to these functions are currently only produced by the OMPIRBuilder
from flang, which already passes the correct number of iterations to
these functions. By adding 1 to the received `num_iters` variable,
worksharing can produce incorrect results. This impacts flang OpenMP
offloading of `do`, `distribute` and `distribute parallel do`
constructs.

Expecting the application to pass `tripcount - 1` as the argument seems
unexpected as well, so rather than updating flang I think it makes more
sense to update the runtime.
