[PATCH] Handle captured statements for predefined expressions

[Wei Pan]

  Comparing to lambdas or blocks, captured statements are statements, no call expression are needed to invoke them. This lets me feel the correct behavior is to use its parent name, rather than the one compiler generated internally.  For OpenMP, with or without pragmas the printed function name should remain the same. This patch implements this. Thanks!
