Subject: [PATCH] intel/compiler: Rotate instructions ROR and ROL cannot have
 source modifiers

I checked the Bspec for both Gen11 and Gen12, and it appears that rotate
instructions cannot have source modifiers or saturate modifer.  Saturate
was already handled.

Fixes: 1e92e83856b ("intel/compiler: Emit ROR and ROL instruction")
