    x86: Cast stride to __PTRDIFF_TYPE__ in AMX intrinsics
    
    On 64-bit Windows, long is 32 bits and can't be used as stride in memory
    operand when base is a pointer which is 64 bits.  Cast stride to
    __PTRDIFF_TYPE__, instead of long.
    
            PR target/106714
            * config/i386/amxtileintrin.h (_tile_loadd_internal): Cast to
            __PTRDIFF_TYPE__.
            (_tile_stream_loadd_internal): Likewise.
            (_tile_stored_internal): Likewise.
    
    (cherry picked from commit aeb9b58225916bc84a0cd02c6fc77bbb92167e53)
