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

Evan Cheng c47620b5d8 Temporary hack to enable more (store (op (load ...))) folding. This makes 
it possible when a TokenFactor is between the load and store. But is still

Chris Lattner d4130375c0 Pull latency information for target instructions out of the latency tables. :) 
Only enable this with -use-sched-latencies, I'll enable it by default with a
clean nightly tester run tonight.

PPC is the only target that provides latency info currently.

Chris Lattner 9df647539d Refactor the priority mechanism one step further: now that it is a separate 
class, sever its implementation from the interface.  Now we can provide new
implementations of the same interface (priority computation) without touching
the scheduler itself.

Chris Lattner fdb533a1f6 Fix a really annoying bug in bugpoint that made reducing C++ testcases 
almost impossible with the new CFE.  It now guarantees that the static

Chris Lattner 207291fd1a Two things: 
1. Don't emit debug info, or other llvm.metadata to the .cbe.c file.
2. Mark static ctors/dtors as such, so that bugpoint works on C++ code
   compiled with the new CFE.
