x86: Cast stride to __PTRDIFF_TYPE__ for AMX-MOVRS intrinsics. [PR122119]

On 64-bit windows, long can't be used, because it is 32 bits. Use
__PTRDIFF_TYPE__ instead of long.

gcc/ChangeLog:

	PR target/122119
	* config/i386/amxmovrsintrin.h
	(_tile_loaddrs_internal): Use __PTRDIFF_TYPE__ instead of long.
	(_tile_loaddrst1_internal): Ditto.
	(_tile_2rpntlvwz0rs_internal): Ditto.
	(_tile_2rpntlvwz0rst1_internal): Ditto.
	(_tile_2rpntlvwz1rs_internal): Ditto.
	(_tile_2rpntlvwz1rst1_internal): Ditto.
