According to the discussion in the loopopt meeting, I've updated the patch such that the `-ppc-loop-prefetch-cache-line` option in powerpc is removed and generalized into the option in TTI that overrides the default and target-specific cacheline size. A powerpc codegen test is updated accordingly.

Summary of this patch is also updated to address a previous comment from Bardia.
