6f8aaf2cb0 Don't generate silly matching code like this:
if (N1.getOpcode() == ISD::ADD &&
     ...)
   if (... &&
       (N1.getNumOperands() == 1 || !isNonImmUse(N1.Val, N10.Val))) &&
       ...)

TableGen knows N1 must have more than one operand.

2046371e70 add some new instructions to the classifier. With this, we correctly insert
a nop into Freebench/neural, which speeds it up from 136->129s (~5.4%).

95a959dc1a Teach instcombine to increase the alignment of memset/memcpy/memmove when
the pointer is known to come from either a global variable, alloca or
malloc.  This allows us to compile this:

  P = malloc(28);
  memset(P, 0, 28);

into explicit stores on PPC instead of a memset call.

a5de484bc7 Split the list scheduler into top-down and bottom-up pieces. The priority
function of the top-down scheduler are completely bogus currently, and
having (future) PPC specific in this file is also wrong, but this is a
small incremental step.
