  [AsmPrinter] Fix handling in emitGlobalConstantImpl for AIX (#116255)

When GlobalMerge creates a MergedGlobal of statics all initialized to
zero, emitGlobalConstantImpl sees a ConstantAggregateZero. This results
in just emitting zeros followed by labels for the aliases. We need to
handle it more like how emitGlobalConstantStruct does by emitting each
global inside the aggregate.
