Regression/Transforms/InstCombine/stacksaverestore.ll

Chris Lattner 356183d91e rename priorityqueue -> availablequeue. When a node is scheduled, remember 
which cycle it lands on.

Chris Lattner 9995a0c019 Move some methods around so that BU specific code is together, TD specific code 
is together, and direction independent code is together.

Chris Lattner 578d8fcb59 merge preds/chainpreds -> preds set 
merge succs/chainsuccs -> succs set

This has no functionality change, simplifies the code, and reduces the size
of sunits.

Nate Begeman d5811b965d Fix PR681 by using the standard Lengauer and Tarjan algorithm for dominator 
set construction, rather than intersecting various std::sets.  This reduces
the memory usage for the testcase in PR681 from 496 to 26MB of ram on my
darwin system, and reduces the runtime from 32.8 to 0.8 seconds on a
2.5GHz G5.  This also enables future code sharing between Dom and PostDom
now that they share near-identical implementations.

Chris Lattner 349e9ddccc Teach the latency scheduler some new tricks. In particular, to break ties, 
keep track of a sense of "mobility", i.e. how many other nodes scheduling one
node will free up.  For something like this:

float testadd(float *X, float *Y, float *Z, float *W, float *V) {
  return (*X+*Y)*(*Z+*W)+*V;
}

For example, this makes us schedule *X then *Y, not *X then *Z.  The former
allows us to issue the add, the later only lets us issue other loads.

This turns the above code from this:

_testadd:
        lfs f0, 0(r3)
        lfs f1, 0(r6)
        lfs f2, 0(r4)
        lfs f3, 0(r5)
        fadds f0, f0, f2
        fadds f1, f3, f1
        lfs f2, 0(r7)
        fmadds f1, f0, f1, f2
        blr

into this:

_testadd:
        lfs f0, 0(r6)
        lfs f1, 0(r5)
        fadds f0, f1, f0
        lfs f1, 0(r4)
        lfs f2, 0(r3)
        fadds f1, f2, f1
        lfs f2, 0(r7)
        fmadds f1, f1, f0, f2
        blr
