According to the OpenMP standard, In a task generating construct, if no default clause is present, a variable for which the data-sharing attribute is not determined by the rules above is firstprivatized. Compiler tries to implement this, but if the variable is not directly used in the task context, this variable may not be firstprivatized. Patch fixes this problem. llvm-svn: 345277
