If a section is supposed to hold elements of type T, then the corresponding CreateSecStartEnd()'s Ty parameter represents T*. Forwarding it to GlobalVariable constructor causes the resulting GlobalVariable's type to be T*, and its SSA value type to be T**, which is one indirection too many. This issue is mostly masked by pointer casts, however, the global variable still gets an incorrect alignment, which causes SystemZ to choose wrong instructions to access the section.
