Subject: [Patch] Splitting memory references during unrolling (resubmission)

Hello,

I fixed the patch according to your comments. 

The diff file is relative to the splitting induction variables 
patch due to the fact it is not in the mainline yet.

Bootstrapped (with -funroll-all-loops) & regression tests on POWER4.

             * loop-unroll.c: (analyze_memory_ref_containing_iv): 
             New function for determine whether the current 
             instruction contains memory reference which uses an
                 induction variable.
                 (analyze_iv_to_split_insn): Expand the function to
                 analyze also instructions of memory references.
