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.

One of these days, I swear I'm going to get the hang of C++ iterators.

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.

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.
