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.
