Chris Lattner f901355379 make sure to mark nodes in the globals graph incomplete after computing it 
so that external globals (and whatever they point to) are marked incomplete.

Chris Lattner d31a3d0e82 Finally fix (the right way) the problem where functions like this: 
void foo() {
  G = 1;
}

would have an empty DSGraph even though G (a global) is directly used
in the function.

Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

This patch is contributed by Gabor Greif, thanks!
