[OpenMP] Add NoSync attributes to alloc / free shared RTL calls

This patch adds the `nosync` attribute to the `__kmpc_alloc_shared` and
`__kmpc_free_shared` runtime library calls. This allows code analysis to
know that these functins dont contain any barriers. This will help
optimizations reason about the CFG of blocks containing these calls.
