MFC r206424: (by rdivacky in 2010)
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.
