[llvm-reduce] ReduceGlobalVarInitializers delta pass: fix handling of globals w/ comdat/non-external linkage

Much like with ReduceFunctionBodies delta pass,
we need to remove comdat and set linkage to external,
else verifier will complain, and our deltas are invalid.

[llvm-reduce] Refactor global variable delta pass

The limitation of the current pass that it skips initializer-less GV's
seems arbitrary, in all the reduced cases i (personally) looked at,
the globals weren't needed, yet they were kept.

So let's do two things:
1. allow reducing initializer-less globals
2. before reducing globals, reduce their initializers, much like we do function bodies
