[Bug rtl-optimization/16803] PowerPC - invariant code motion could be removed from loop.

Branch on count is not used since we do not know whether the loop is not 
infinite (which would be the case if y == MAX_INT - SOME_CONST).

The fact that neither of the two rtl loop invariant motion passes nor PRE moves 
the invariants out of the loop is weird.  I will have a look at that.
