- Global vector variables expose the vector ABI through their alignments only if they are >=16 bytes in size. - Vectors passed between functions expose the vector ABI only if they are <=16 bytes in size. LLVM test suite builds with gcc/clang now give the same gnu attributes emitted. Reviewed By: Ulrich Weigand Differential Revision: https://reviews.llvm.org/D141409
