Subject: [PATCH] [OpenMPIRBuilder] Remove wrapper function in `createTask`
This patch removes the wrapper function in
`OpenMPIRBuilder::createTask`. The outlined function is directly of the
form that is expected by the runtime library calls. This also fixes the
global thread ID argument, which should be used whenever
`kmpc_global_thread_num()` is called inside the outlined function.
