[AMDGPU] Implement widening multiplies with v_mad_i64_i32/v_mad_u64_u32

[foad]

Summary

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.

[foad]

The change in the instruction mix in the generated lit tests looks like this:

$ git show | awk '/^-/&&$3~/[sv]_/{a[$3]--}/^+/&&$3~/[sv]_/{a[$3]++}END{for(i in a)if(a[i])printf"%+d %s\n",a[i],i}' | sort -n
-604 v_mul_hi_u32
-567 v_mul_lo_u32
-31 s_mul_i32
-15 v_mul_hi_i32
-10 s_and_b32
-4 v_cndmask_b32_e32
-2 s_mov_b32
-2 v_cmp_ne_u32_e32
-2 v_lshlrev_b32_e32
-2 v_lshrrev_b32_e32
-2 v_mov_b32_e32
+15 v_mad_i64_i32
+1 v_mul_hi_i32_i24_e32
+20 v_addc_u32_e32
+21 v_add_i32_e32
+2 s_waitcnt
+2 v_cmp_ne_u32_e64
+2 v_mul_i32_i24_e64
+2 v_mul_u32_u24_e64
+4 v_cndmask_b32_e64
+4 v_mul_i32_i24_e32
+4 v_mul_u32_u24_e32
+617 v_mad_u64_u32

So it is mostly replacing v_mul_hi_u32+v_mul_lo_u32 with v_mad_u64_u32.

GlobalISel version?

Could this try to do better than 0 if the source is an add?

Seems missing a subtarget check, I'm pretty sure gfx6 didn't have mad_u64_u32

GlobalISel version?

Yes that would be nice, but GlobalISel doesn't seem to have a GMIR opcode corresponding to [su]mul_lohi, at least not yet, so I'm not sure what the best approach would be. Anyway this patch is big enough already so I'd prefer to keep it for SelectionDAG and work on GlobalISel later.

No, not if the source is an add. It would have to be if the result is used in an add, like what SITargetLowering::performAddCombine does for i64 mul. That's the further improvement I alluded to in the commit message.

Good point, will fix.

Add missing subtarget check.
