Subject: 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.
