Loop reversal doesn't occur yet.

Dunno if tree loop reversal is already there, but Zdenek probably likes to know
what bugs he is fixing...

IIRC loop.c does the reversal so we need to move to the tree level.

Confirmed, on ppc-darwin we do reverse the loop and we use the do-loop patterns:
L4:
lfsx f0,r2,r4
add r2,r2,r7
stfsx f0,r3,r0
add r0,r0,r6
bdnz L4
L11:
lfsx f
