Jin Lin	cedfa38fc4	Preserve the lexical order for global variables during llvm-link merge The order of global variables is generated in the order of recursively materializing variables if the global variable has the attribute of hasLocalLinkage or hasLinkOnceLinkage during the module merging. In practice, it is often the exact reverse of source order. This new order may cause performance regression. The change is to preserve the original lexical order for global variables.

Preserve the lexical order for global variables during llvm-link merge

The order of global variables is generated in the order of recursively materializing variables if the global variable has the attribute of hasLocalLinkage or hasLinkOnceLinkage during the module merging. In practice, it is often the exact reverse of source order. This new order may cause performance regression.

The change is to preserve the original lexical order for global variables.

Correctly handle llvm.global_ctors merging.

We were not handling the case where an entry must be dropped and the
destination module has no llvm.global_ctors.
