llvm: Match new LLVM 128-bit integer alignment on sparc
LLVM continues to align more 128-bit integers to 128-bits in the data layout rather than relying on the high level language to do it. Update SPARC target files to match and add a backcompat replacement for current LLVMs. See llvm/llvm-project#106951 for details
