Seen also on powerpc64-linux. The problem here is that the vsx_splat_V2DF/V2DI
load and store instructions only support mem[reg] or mem[reg+reg] addressing,
but the MEM mode is not a vsx vector mode. So reg_offset_addressing_ok_p used
in rs6000_legitimate_address_p and other address predicates returns true,
wrongly allowing lo_sum addresses.
