42547124d0 - Dramatically simplify the ConstantMerge code now that 
Value::replaceAllUsesWith works with constants correctly.

266bacb650 - Make Value::replaceAllUsesWith work with constants correctly. This fixes 
bug FuncResolve/2002-08-19-ResolveGlobalVars.ll and gzip looks better.

0acdba0025 - Add new Constant::replaceUsesOfWithOnConstant which has an end result 
similar to User::replaceUsesOfWith but actually does the right thing for
    constants.

83d105d986 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.

40df2d9d4c - 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.
