aarch64 : Mark rotate immediates with '#' as per DDI0487iFc.

The armv8_arm manual [C6.2.226, ROR (immediate)] uses a # in front
of the immediate rotation quantity.

Although, it seems, GAS is able to infer the # (or is leninent about
its absence) assemblers based on the LLVM back end expect it.

gcc/ChangeLog:

	* config/aarch64/aarch64.md (<optab>_rol<mode>3): Add a '#'
	mark in front of the immediate quantity.
	(<optab>_rolsi3_uxtw): Likewise.
