    Rename the ALIGN macro to LINT_ALIGN so it does not clash with
    machine/param.h
  
    Bump the alignment to 16bytes because lint1 memory allocator is used for
    objects that require 16bytes alignment on amd64 (ie. val_t). This makes
    lint1 work when compiled with compiler(s) that use SSE for memcpy on amd64.
    (e.g. clang).
  
  This allows me to compile stable-8 on a 64-bit build host running 10-stable,
  without dying during the xlint build.  It should work fine on 11-current too.
