With the abs patterns gone, and the ne0 patterns fixed, mainline
now generates
li 10,1
lis 9,0xcf8
ori 9,9,63
sld 3,10,3
and 3,3,9
addic 9,3,-1
subfe 3,9,3
blr
which is the expected code. It would be nice if we could get
the 4.1 code back, but that's a separate problem (and not a
target problem I think).
