Log:
Fix nystrom alias csig fault when setup onstraint graph for OpenMP lower
generated PU.
This problem is when creating constraint graph for OpenMP parallel PU.
Compilation has sig fault when checking if a WN node can be a pointer.
The root cause is WN node has constraint graph node id, however id's
corresponding node not in current contraint graph.
Because when OpenMP lower clone the parallel PU, it copy the
WN_MAP_ALIAS_CGNODE map.
Fix is in OpenMP lower, not copy the WN_MAP_ALIAS_CGNODE map.
