aco: Use movk for AddressHi bits in vertex prolog

Browse source 
Eliminates a useless extra dword by transforming
        s_mov_b32 s47, 0xffff8000                                   ; beaf03ff ffff8000
to
        s_movk_i32 s47, 0x8000                                      ; b02f8000

which does the same thing.
