Prior to this patch, the LLVMContext was shared across inputs to llvm-dis. Consequently, NamedStructTypes was shared across inputs, which impacts StructType::setName - if a name was reused across inputs, it would get renamed during construction of the struct type, leading to tricky to diagnose confusion.
