[clang] [llvm] Global string alignment (PR #142346)

I'm not sure this is the right fix for the issue. Just like for allocas, the global variable alignment is a *minimum* required alignment, which can and should be raised by targets if it improves code generation. (The exception to this is if the global has a section.)

It looks like CGP has a shouldAlignPointerArgs hook for this purpose, but that seems overly specific for what is desired here. I'm surprised we don't seem have something more generic for this...
