dade2d22ba Two bug fixes: 
1. Actually increment the Statistic for the GV elim optzn
 2. When resolving undef branches, only resolve branches in executable blocks,
    avoiding marking a bunch of completely dead blocks live.  This has a big
    impact on the quality of the generated code.

With this patch, we positively rip up vortex, compiling Ut_MoveBytes to a
single memcpy call. In vortex we get this:

     12 ipsccp           - Number of globals found to be constant
    986 ipsccp           - Number of arguments constant propagated
   1378 ipsccp           - Number of basic blocks unreachable
   8919 ipsccp           - Number of instructions removed

56c5d7369b Bools are *also* not ints. Sigh. Furthermore, most of the TargetMachine 
ctor parameters can be defaulted.

Print the transformed llvm code input to the instruction selector
when -print-machineinstrs is on, just like V9.

 or  0, x      add  0, x

4f70b63ebc Make GEPs not suck so much: 
* Don't emit the Index * ElementSize multiply if Index is a constant.
* Use a shift, not a multiply, if ElementSize is 1/2/4/8.
* If ElementSize fits in the immediate field of SMUL, then put it there.

Fix a bug where struct offsets might be truncated (ConstantSInt::get is
now used instead of ConstantInt::get).

59acc7d4ef This is the initial implementation of IPSCCP, as requested by Brian. 
This implements SCCP/ipsccp-basic.ll, rips apart Olden/mst (as described in
PR415), and does other nice things.

There is still more to come with this, but it's a start.

c4d6916508 Eliminate this ugly hack. This was put back in when replaceAllUsesOf used 
a different algorithm that was extremely inefficient for instructions with
many operands.

This reduces the time of this code snippet from .23s for 176.gcc to 0.03s
in a debug build, which speeds up total llvm-dis time just barely.

It's more of a code cleanup than a speedup.

ea1c45405d Do extremely simple sinking of instructions when they are only used in a 
successor block.  This turns cases like this:

x = a op b
if (c) {
  use x
}

into:

if (c) {
  x = a op b
  use x
}

This triggers 3965 times in spec, and is tested by
Regression/Transforms/InstCombine/sink_instruction.ll

This appears to expose a bug in the X86 backend for 177.mesa, which I'm
looking in to.
