9c72319938 Fix PR557 and basictest[34].ll.
This makes reassociate realize that loads should be treated as unmovable, and
gives distinct ranks to distinct values defined in the same basic block, allowing
reassociate to do its thing.

120347e8d1 Strength reduce SAR into SHR if there is no way sign bits could be shifted
in.  This tends to get cases like this:

  X = cast ubyte to int
  Y = shr int X, ...

Tested by: shift.ll:test24

c0649ac931 Rewrite the guts of the reassociate pass to be more efficient and logical. Instead
of trying to do local reassociation tweaks at each level, only process an expression
tree once (at its root).  This does not improve the reassociation pass in any real way.

29a5bf5f0f * Break tests into individual cases so its easier to see what's going on.
* Add four new cases to handle the new optimizations for strlen, dealing
  with:
    strlen(x) != 0 -> *x != 0
    strlen(x) == 0 -> *x == 0
  for each of two cases: strlen(x) != 0 and strlen(x) == 0

Reid Spencer
789082af03 * Add two strlen optimizations:
strlen(x) != 0 -> *x != 0
    strlen(x) == 0 -> *x == 0
* Change nested statistics to use style of other LLVM statistics so that
  only the name of the optimization (simplify-libcalls) is used as the
  statistic name, and the description indicates which specific all is
  optimized. Cuts down on some redundancy and saves a few bytes of space.
* Make note of stpcpy optimization that could be done.
