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.

- 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.
