d99bf49a53 Split mem2reg promotion into two parts: a function which does the work, and
a pass which wraps the function.  This allows other passes to use the functionality

* A & ~A == 0
  * A / (2^c) == A >> c  if unsigned
  * 0 / A == 0
  * 1.0 * A == A
  * A * (2^c) == A << c
  * A ^ ~A == -1
  * A | ~A == -1
  * 0 % X = 0
  * A % (2^c) == A & (c-1) if unsigned
  * A - (A & B) == A & ~B
  * -1 - A == ~A

e12c74c07b This file implements a pass that automatically parallelizes a program,
using the Cilk multi-threaded runtime system to execute parallel code.
The current version inserts too many sync() operations in the program
because it does not attempt to optimize their placement.

a45ec54a02 Almost a complete rewrite of FunctionResolution to now resolve functions
and global variables.

This fixes bug: FuncResolve/2002-08-19-ResolveGlobalVarsEasier.ll
And bug: SingleSource/UnitTests/2002-10-09-ArrayResolution.c

Note that this does not fix bug:
FunctionResolve/2002-08-19-ResolveGlobalVars.ll because replaceAllUsesWith
breaks when a constantexpr is pointing to the thing being replaced.  This
is more of an infrastructure problem than anything.

f7f009d9a5 - Checkin LARGE number of Changes to CEE pass that will make it much more
powerful, but that are largely disabled.  The basic idea here is that it
    is trying to forward branches across basic blocks that have PHI nodes in
    it, which are crucial to be able to handle cases like whet.ll.
    Unfortunately we are not updating SSA correctly, causing sim.c to die, and I
    don't have time to fix the regression now, so I must disable the
    functionality.

952eaee239 Hoist the contents of Loops in depth first order in the dominator tree,
rather than in random order.  This causes LICM to be DRAMATICALLY more
effective. For example, on bzip2.c, it is able to hoist 302 loads and
2380 total instructions, as opposed to 44/338 before.  This  obviously
makes other transformations much more powerful as well!

e4314ed315 Fix: ConstantMerge/2002-09-23-CPR-Update.ll
Basically, this bug boiled down to calling replaceUsesOfWith on a constant,
which changed it's shape in an illegal way.  This pass now goes through all
of the trouble neccesary to do the replacement on constants.

520eaff91a Following Chris's advice, I'm pruning some unnecessary .h includes that I'm
noticing. Since Module includes Function, and eventually, BasicBlock and
GlobalVariable, the last three are unnecessary to be included directly.
