We were previously genrating nonsense code if the destination != source:
faddp v2.4s, v4.4s, v4.4s
faddp s2, v4.2s
The result of the first faddp is ignored, so the second merely calculates the
sum of the first 2 sources (not all 4 as needed).
The correct fix is to feed the first add into the second, regardless of the
final destination:
faddp v2.4s, v4.4s, v4.4s
faddp s2, v2.2s
Hit in an ASM test with new RA.
