Hmm, I'll have to keep this in mind when I'm fixing
http://llvm.org/bugs/show_bug.cgi?id=21511 soon... (previously there was
only one caller of getOrCreateGlobalVariableDIE and it didn't actually use
the return value - granted, this caller will never pass a DW_TAG_member,
unlike the existing caller which may/will have to be updated to pass those
too... anyway)
