[ARM] Fix Neon vector type alignment to 64-bit This is restricted version of patch - https://reviews.llvm.org/D33205 that I reverted as it was leading to ABI breaks on darwin etc. This patch restricts the fix to AAPCS (Android remains 128-bit). Reviewed by: Renato Golin, Stephen Hines Differential Revision: https://reviews.llvm.org/D33786 llvm-svn: 304889
