  Log Message:
  -----------
  [OPENMP]Do not capture base pointer by reference if it is used as a base for array-like reduction.

If the declaration is used in the reduction clause, it is captured by
reference by default. But if the declaration is a pointer and it is a
base for array-like reduction, this declaration can be captured by
value, since the pointee is reduced but not the original declaration.
