b5027095e5 - Eliminated the deferred symbol table stuff in Module & Function, it really 
wasn't an optimization and it was causing lots of bugs.

82f54dca49 - Change Function's so that their argument list is populated when they are 
constructed.  Before, external functions would have an empty argument list,
    now a Function ALWAYS has a populated argument list.

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.
