We would like to contribute the Integer/FP scalar reduction optimization from Intel.
The contribution is referenced as Bug ID 8074981 as a performance enhancement.
Please review this patch:
The optimization achieves as much as 2.3x on integer reductions and supports float and double precision optimizations
which also have significant optimization uplift an obey strict fp constraints.
Nils Eliasson has offered to sponsor this patch.
