Michael Zolotukhin 8bb31dd08a [Unroll] Follow-up for r247769: fix a bug in UnrolledInstAnalyzer::visitLoad. 
Apart from checking that GlobalVariable is a constant, we should check
that it's not a weak constant, in which case we can't propagate its
value.

Michael Zolotukhin fc314be0ec [Unroll] Fix a bug in UnrolledInstAnalyzer::visitLoad. 
We only checked that a global is initialized with constants, which is
incorrect. We should be checking that GlobalVariable *is* a constant,
not just initialized with it.
