do it on povray. The problem is that we were not copying globals from callees to

Two changes:
...
1. Functions do not make things incomplete, only variables
2. Constant global variables no longer need to be marked incomplete, because
we are guaranteed that the initializer for the global will be in the
graph we are hacking on now. This makes resolution of indirect calls happen
a lot more in the bu pass, supports things like vtables and the C counterparts
(giant constant arrays of function pointers), etc...

Instead of cloning the globals for main into the globals graph at the end of

BU propagation, clone the globals into the GG of EACH FUNCTION that finishes
processing! The GlobalsGraph *must* include all globals and effects from
all functions in the program. Fixing this makes pool allocation work better
on 175.vpr, but it still ultimately crashes.
