Joseph Huber 0870a4f59a [OpenMP] Add flag for disabling thread state in runtime
The runtime uses thread state values to indicate when we use an ICV or
are in nested parallelism. This is done for OpenMP correctness, but it
not needed in the majority of cases. The new flag added is
`-fopenmp-assume-no-thread-state`.
