New HPF Reduction Functions

There are four FUNCTION s in this class:

• IALL, corresponds to IAND reduction,
• IANY, corresponds to IOR reduction,
• IPARITY, corresponds to IEOR reduction,
• PARITY, corresponds to .NEQV. reduction,

Like all reductions, each function has optional DIM and MASK arguments. These work in exactly the same way as for the SUM and PRODUCT reductions.

IALL, IANY and IPARITY are all bit manipulation functions. PARITY operates on logical values. All are elemental.
