Architecture-specific section alignment
Tests found excessive cache thrashing on x86-64 architectures. The
problem was traced to the alignment of sections. This patch sets up
an architecture-specific alignment of 512 bytes for x86-64 and 16
bytes for all others. It uses preprocessor directives that, hopefully,
make it easy to tweak for other architectures.
