[AMDGPU] Implement widening multiplies with v_mad_i64_i32/v_mad_u64_u32

Select SelectionDAG ops smul_lohi/umul_lohi to
v_mad_i64_i32/v_mad_u64_u32 respectively, with an addend of 0.
v_mul_lo, v_mul_hi and v_mad_i64/u64 are all quarter-rate instructions
so it is better to use one instruction than two.

Further improvements are possible to make better use of the addend
operand, but this is already a strict improvement over what we have
now.
