nir, intel/compiler: Add support for ROR/ROL instructions
For Gen >= 11, add support for rotate [Right/Left] instructions. There are no shaders in shader-db which can benefit from this change.
Tested these changes with piglit!74 (merged)
nir: Add lower_rotate flag and set to true in all drivers enable the other drivers to lower rotate instruction which are not prepared to handle it.
Thanks to @mattst88 for suggesting/helping me on this exercise.
