If you don't have autoupgrade, that means you can't link IR built with older versions of LLVM to IR built with newer versions.  llvm::UpgradeDataLayoutString is designed to fix this incompatibility.  It's probably worth doing here given that it's relatively straightforward.

The issue with the i128 datalayout ugrade isn't the datalayout string itself, it's that the datalayout change affects existing code in a non-trivial way.  That isn't really an issue here: there shouldn't be any existing AArch64 IR using address-space 270, so changing its meaning won't have any effect.
