These instructions used to use rotl with a bitwidth-1 immediate. I changed the immediate to 1, but failed to change the opcode. Thankfully this seems to have not caused a functional issue because we now had two rotl by 1 patterns, but the correct ones were earlier and took priority. So we just missed some optimization. llvm-svn: 356164
