[Bug rtl-optimization/84164] [8 Regression] ICE: in elimination_costs_in_insn, at reload1.c:3633 at -O1


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84164

--- Comment #2 from ktkachov at gcc dot gnu.org ---
We encounter an unrecognizable insn:
(insn 59 58 43 7 (set (reg:DI 124)
        (rotatert:DI (reg:DI 125 [ c ])
            (subreg:QI (and:SI (reg:SI 128)
                    (const_int 65535 [0xffff])) 0))) "ice.c":8 -1


It comes from the *aarch64_reg_<mode>3_neg_mask2 splitter. Need to figure out
what went wrong there
