28b7c7feab Add a utility script to find a mis-optimization problem. This sometimes
helps when bugpoint can't find the problem directly because it needs the
set of optimizations that cause the program to fail.

892aaf8d74 Divide select methods into groups by SelectionDAG node opcodes (ISD::ADD,
X86ISD::CMP, etc.) instead of SDNode names (add, x86cmp, etc). We now allow
multiple SDNodes to map to the same SelectionDAG node (e.g. store, indexed
store).

03fa6ea402 - When performing pre-/post- indexed load/store transformation, do not worry

  address pass split it back to non-indexed ops.

5d056952ba optimize single MBB loops better. In particular, produce:
LBB1_57:        #bb207.i
        movl 72(%esp), %ecx
        movb (%ecx,%eax), %cl
        movl 80(%esp), %edx
        movb %cl, 1(%edx,%eax)
        incl %eax
        cmpl $143, %eax
        jne LBB1_57     #bb207.i
        jmp LBB1_64     #cond_next255.i

intead of:

LBB1_57:        #bb207.i
        movl 72(%esp), %ecx
        movb (%ecx,%eax), %cl
        movl 80(%esp), %edx
        movb %cl, 1(%edx,%eax)
        incl %eax
        cmpl $143, %eax
        je LBB1_64      #cond_next255.i
        jmp LBB1_57     #bb207.i

This eliminates a branch per iteration of the loop.  This hurted PPC
particularly, because the extra branch meant another dispatch group for each
iteration of the loop.
