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. Reviewed By: jdoerfert Differential Revision: https://reviews.llvm.org/D109995
