[SPARC] Align i128 to 16 bytes in SPARC datalayouts (#106951)
Align i128s to 16 bytes, following the example at
https://reviews.llvm.org/D86310.
clang already does this implicitly, but do it in backend code too for
the benefit of other frontends (see e.g
https://github.com/llvm/llvm-project/issues/102783 &
https://github.com/rust-lang/rust/issues/128950).
