Looks like a single bit in the facility bit string is being used to

bit 45 in the facility bit string says this (page 4-68):
"The distinct-operands, fast-BCR-serialization, high-word,
interlocked-access, load/store-on-condition, and population-count
facilities are installed in the z/Architecture architectural mode."
