Add a per target max vector alignment field (e.g., 32-byte alignment for x86 due to
AVX). Currently, if no aligned attribute is specified the alignment of a vector is inferred from its size. Thus, very large vectors will be over-aligned with no benefit. Target owners should set this target max. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160209 91177308-0d34-0410-b5e6-96231b3b80d8
