66cbf54030 If a loop termination compare instruction is the only use of its stride, 
and the compaison is against a constant value, try eliminate the stride
by moving the compare instruction to another stride and change its
constant operand accordingly. e.g.

loop:
...
v1 = v1 + 3
v2 = v2 + 1
if (v2 < 10) goto loop
=>
loop:
...
v1 = v1 + 3
if (v1 < 30) goto loop

402c11966a This was failing on Darwin, which defaults to PIC; 
no lea was generated.  I think this follows the intent.

348195148a switch some calls to SelectionDAG::getTargetNode to use

34c16a1b2d Lowering a memcpy to the stack is killing PPC. The ARM and X86 backends already 
have their own custom memcpy lowering code. This code needs to be factored out
into a target-independent lowering method with hooks to the backend. In the
meantime, just call memcpy if we're trying to copy onto a stack.
