New description:

 The Intel compiler does not handle workshare constructs well. The attached
 patch replaces them by explicit loops, which execute faster. This makes a
 measurable difference on Hopper with 24 OpenMP threads.

 This only modifies one operator; other operators could be treated in the
 same way.
