Youre refering to this bit from the Redpiece: The z196 new instruction set architecture (ISA) includes 110 new instructions added to improve compiled code efficiency: High-Word Facility (30 new instructions), with independent addressing to high word of 64 bit GPRs, and effectively provides compiler/ software with 16 additional 32 bit registers. Interlocked-Access Facility (12 new instructions), including interlocked (atomic) load, value update and store operation in a single instruction, with immediate exploitation by Java. Load/Store-on-Condition Facility (6 new instructions), with load or store conditionally executed based on condition code, achieving dramatic improvement in certain codes with highly unpredictable branches. Distinct-Operands Facility (22 new instructions), with independent specification of result register (different than either source register), reducing register value copying. Population-Count Facility (1 new instruction), which is a hardware implementation of bit counting, achieving up to five times faster than prior software implementations. Integer to/from Floating point converts (39 new instructions). Sounds interesting. But you have found the first description of new instructions I've heard of.
