LHLR R1,R2 is the "perfect" match, and LLHFR is the inverse. These are extended mnemonics, and actually generate RISBHGZ or RISBLGZ instructions (which are not for the faint of heart, in all their native glory). These are documented (along with some other varieties) in PoOp, page 7-137, or just before the SRST instruction.
