peter 976bb368f6 For the amd64 we need to do some extra stack alignment fixups. Otherwise
we can end up with some threads with a non-16-byte-aligned stack.  This
causes some interesting side effects, including general protection
faults leading to a SIGBUS when doing floating point or varargs.  This
should be just a verbose NOP for the other platforms.
