improves the post ra mad folding pass:
total instructions in shared programs : 2811662 -> 2808429 (-0.11%)
total gprs used in shared programs : 379273 -> 379236 (-0.01%)
total local used in shared programs : 9505 -> 9505 (0.00%)
total bytes used in shared programs : 25773432 -> 25743616 (-0.12%)
local gpr inst bytes
helped 0 26 1736 1736
hurt 0 20 78 78
v2: reorder to show the benefit of this patch
